Charger for cars on IR2153. Push-pull charger for any batteries

For car batteries. There are a lot of schemes for such attachments - some people need to choose for the best of all the handy elements, and other victorious blocks are ready, for example, from computers. Living block personal computer can be recycled in a full battery charger for a car battery without special chargers. Literally in a couple of years, you can add attachments, in which you can measure the voltage of life and charge. It is better to add fittings to the design for wiping.

Main characteristics of chargers

1. Transformer ones - they have a large load and dimensions. The reason is that the transformer is victorious - the new value of the winding has that heart of electrical steel, which has a great load.
2. Impulses about such attachments are more positive - the dimensions of the attachments are small, the wall is also small.

For its compactness, it was worthy of the slow chargers of the impulse type. Ale krim tsgogo, they have a higher KKD in pairs with transformers. You can sell more than this type Impulse Circuits the stinks are similar in tantrums, the stench exudes less vicarious elements.

Charger design elements

For the help of a charger, I will confirm the practicality of the battery. The design has a victorious modern elemental base. The warehouse includes the following blocks:

1. Impulse transformer.
2. Vibrating block.
3. Stabilizer block.
4. Fit for vimiryuvannya struma charging that (or) voltage.
5. The main unit that allows you to control the charging process.

All these elements may have small dimensions. The pulse transformer is not large, the windings are wound on ferrite cores.

Best simple designs pulse chargers for Hyundai car batteries or other brands of cars can be charged with only one transistor. Golovne - to develop a control circuit for this transistor. All components can be purchased at the radio parts store or taken from PC, TV, monitor units.

Features of the robot

According to the principle of work, all schemes of impulse chargers for car batteries can be divided into the following subgroups:

1. Charging the battery with a voltage, strum at what may be a constant value.
2. The voltage remains constant, but the strum changes incrementally when charging.
3. Combination method - combining the first two.

The best way is to change the strum, not the voltage. Vin suitable for larger batteries. But theoretically, the shards of the chargers can help control the power of the struma even less, as the voltage on the output is constant.

Features of charging modes

If the strum becomes permanent, and the voltage changes, then you take away a lot of problems - the plates in the middle of the battery will sag, which will bring you out of tune. In this case, the battery is not visible, it will be more than enough to buy a new one.

The most sparing mode is the combinations, with some kind of slow charging for the help of a steady stream. At the end of the process, a change in the struma and stabilization of the voltage are required. For the help of which the ability to boil the battery is reduced to a minimum, gases are also less visible.

How to choose a charger?

In order for the battery to last longer, it is necessary to correctly select the impulse charger for the car battery. In the instructions before them, all the parameters are specified: charging jet, voltage, navit schemes to be guided.

Make sure that the charger is responsible for vibrating the strum, that 10% of the total capacity of the battery is healthy. You also need to pay the following factors:

1. Obov'azkovo insure the seller, if possible specific model The charger will renew the battery's performance. The problem is that not all buildings are built to work. If your car has a 100 A * year battery, and you buy a charger with a maximum stream of 6 A, then it will be insufficient.
2. From the first point, it’s respectful to wonder, what is the maximum strum you can see attachments. Let's not take care of the voltage - the deacons can see not 12, but 24 Volts.

Bazhano, so that the charger had a function automatic switch-on when the battery is fully charged. For the help of such a function, you will save yourself some problems - you will not need to control charging. As soon as you reach the maximum charge, attach yourself to join.

Obov'yazkovo under the hour of operation of such devices can cause problems. No matter what happened, follow simple recommendations. Golovna - make sure that the banks of the battery have enough electricity.

If yoga is not enough, then add distilled water. Filling with clean electrolyte is not recommended. Obov'yazkovo insure the following parameters:

1. The magnitude of the charging voltage. The maximum value can be changed to 14.4 U.
2. The magnitude of the struma force - this characteristic can be adjusted without special zusil on impulse chargers for car batteries "Orion" and similar ones. For which, an ammeter and a changeable resistor are installed on the front panel.
3. Trivality of charging the battery. It is important to understand for the presence of indicators, if the battery is charged, and if it is discharged. Connect the ammeter between the charger and the battery - as this indication does not change and is marginally small, it is necessary to note about those that the charging has changed.

If the BV didn’t beat the charger, try not to overdo it - don’t trim the battery more. Otherwise, the electric current may start to boil.

Self-contained outbuildings

As a basis, you can take the scheme of a charging impulse attachment for car batteries "Aida" or similar ones. Even more often in self-confidence zastosovuyut circuit IR2153. Її on the vіdmіnu vіd decide, yakі vikoristovuyutsya preparation of chargers, somu, scho not two capacitors are installed, but one - electrolytic. But such a scheme may be one short - with help, you can only build low-power outbuildings. But the problem is overcome by the installation of hardened elements.

In all designs, for example, 8N50 is stuck. The body of these fittings is insulated. Diode bridges for self-contained chargers are better than vikoristovuvaty, as they are installed in power supply units of personal computers. As there is no ready-made bridge assembly, it is possible to build some of the conductor diodes. Bazhano, they say that the value of the strumum they have is a bull for 10 amperes. Alece for vipadkіv, if the charger vikoristovuvatimetsya with rechargeable batteries єmnіstyu not more than 70-8-0 A * year.

Lanciug living battery charger

In impulse chargers for Bosch car batteries, the same type of devices are vicorated in the circuit of the lancet, a resistor for extinguishing the struma. If you have done it yourself, prepare a charger, you need to install a resistor with a support of about 18 kOhm. Far behind the circuit there is a direct block of a single-phase type. At the new one, more than one conductive diode is installed, after which an electric capacitor is installed.

Vіn nebhіdniy in order to change the storage jet. Bazhan vikoristovuvati keram_chnі chi plіvkovі elements. Behind Kirchhoff's laws, substitution schemes are formed. In the mode of a changeable stream, the capacitor is replaced by a conductor. And with a robotic scheme on a constant stream, it is a roaring. Later, the straightened streamer after the diode will have two warehouses: the main one - constant strum, and bring in the leftovers of the minty, take them away.

Pulse transformer

The design of the charging impulse attachment for car batteries "Koto" has a special design transformer. For self-sufficient, you can quickly prepare - take it from the block of life of a personal computer. The stinks of zastosovuyutsya transformers, which are ideally suited for the implementation of schemes for charging attachments - stinks can create a high stream.

Also, they allow you to keep an eye on the value of the voltage at the output of the charger. Diodes, like they are installed after the transformer, can be the most impulsive, otherwise they simply cannot work in the circuit. The stench is quick to see the fret, squirming in the straightening of the high-frequency strum. As a filtering element, it is necessary to install a spear of electrical capacitors and an RF choke. It is recommended to plug the thermistor with a 5 ohm support to ensure a low charge rate.

Before speech, the thermistor can also be found in the old PSU from the computer. To pay attention to the capacity of an electric capacitor - it is necessary to take it out of the magnitude of the tightness of the entire outbuilding. For skin 1 watt of tension, 1 microfarad is required. The working voltage is not less than 400 V. You can put in chotiri elements of 100 microfarads of leather, connected in parallel. For such a charge, there is a lot of confusion.

For a long time I was praised by the topic of how it is possible to beat the block of life in the form of a computer as a support for tightness. Ale rework the block of life - it’s still a rozvaga, especially impulsive with such a smart installation. Even though I’m ready for all sorts of fireworks, but I didn’t want any homemade lyakati, that’s not safe for myself.

Zagalom simple solution, which does not mean any special details and no taxation. Zіbrav-vvіmknuv-pratsyuє. She wanted to practice at the stained glass other boards for the help of photoresist, shards of the rest of the hour today laser printers became greedy for toner, and the primary laser-pure technology did not work out. As a result of the work with the photoresist, I was left with more satisfaction - for the experiment on the plate of the glass windows, I wrote a line of 0.2 mm. I won miraculously! So, to finish the preludes, I will describe the scheme of the process of folding and refining the block of life.

The block of living is really even simpler, the selection is practically all of the details that have been lost after the selection of not the best pulser from the computer, - from quiet, for example, “do not add” details. One of these details is a pulse transformer, which can be rewound without rewinding in a 12V block, or re-wired, which can also be just a matter of stress, for which I have rewound Moskatov's program.

Scheme of the block of the impulse block of life:

How are the components of the vikoristan?

ir2153 driver - a microcircuit that works in pulse converters for life fluorescent lamps, її more current analogue - ir2153D and ir2155. For different devices ir2153D, the VD2 diode can be turned off, the shards of the wines are already in the microcircuit. All microcircuits of the 2153 series have a 15.6V zener diode installed in the lancet, so it does not bother much with the addition of a voltage stabilizer for the driver's life;

VD1 - whether it's a vipryamlyayuchy іz zavorotnoy naprugoyu no lower than 400V;

VD2-VD4 - “swidcode”, with a small renewal time (no more than 100ns) for example - SF28; In fact, VD3 and VD4 can be turned off, I don’t set them;

yak VD4, VD5 - double-voltage double diode in the computer block of life "S16C40" - the same "Schottky" diode, you can put whether it is any other, less strained. The winding is required for the life of the ir2153 driver after the impulse changeover is started. It is possible to turn off the diode and the winding, so it is not planned to increase the voltage over 150W;

Diodes VD7-VD10 - "Schottky" diodes, for voltage not lower than 100V and stream not less than 10 A, for example - MBR10100, or else;

transistors VT1, VT2 - whether it's hard to see if it's hot, if it's too tight to lie low, but it's not too hot here, so you know more than 300W from the block;

L3 - windings on a ferite shear and sweeping 4-5 turns of a 0.7mm wire; Tsey lance (L3, C15, R8) can be switched off in the blink of an eye, wine is needed, so that the operation mode of the transistors will be slightly easier;

Throttle L4 windings on the kіlts_ vіd old choke group stabilization of the same block of life vіd computer, and avenge 20 turns, wind with a twin dart.

Capacitors at the input can be supplied with less capacitance, their capacitance can be approximately 1-2 microfarads per 1 W of intensity. Do not splurge on capacitors and put on the output of the block a capacity greater than 10,000 microfarads, so that you can bring it to a "salute" when it is turned on, shards of stink when it is turned on, indicate a significant stream for charging.

Now a piece of information about the transformer. The parameters of the pulse transformer are assigned to the Moskatov program and are suitable for a W-like core with offensive denim: S0 = 1.68 sq. Sc = 1.44 sq. Lav. = 86cm; Conversion frequency - 100kHz;

Otrimanі rozrahunkovі data:

Winding 1- 27 turns 0.90 mm; voltage - 155V; Wound in 2 balls with a dart, which consists of 2 cores of 0.45 mm each; The first ball is the inner revenge of 14 turns, the other ball is the outside revenge of 13 turns;

winding 2- 2 halves of 3 turns with a 0.5mm dart; tse - “self-energizing winding” at a voltage of close to 16V, it is wound with a dart so that the windings are wound in different sides, the middle point is displayed as a name and is connected to the board;

winding 3- 2 halves of 7 turns, also wound with a bagatozhilny wire, one half in one coil, then through the ball of insulation - the other half, in the opposite coil. The ends of the windings are called into the "braid" and are connected to the main point on the board. The winding is designed for a voltage close to 40V.

In the same rank, you can loosen the transformer for whether I need a voltage. I have chosen 2 such blocks of life, - one - for the power supply on TDA7293, the other - for 12V for power life, - it works like a laboratory one.

Living block for podsilyuvach on a voltage of 2x40V:

Impulse block of life for 12V:

Block of living near the collection in the building:

A photo of the testing of the impulse block of life - the one that for the auxiliary power supply for the additional equivalent of the voltage of the MLT-2 decals of 10 Ohm resistors, which is included in a different sequence. The method used to take data about strain, voltage drop and voltage difference at the shoulders +/- 40V. For subbags, I had the following parameters:

Intensity - close to 200W (do not know more);

voltage, fallow input - 37.9-40.1V in the entire range from 0 to 200W

Temperature at the maximum intensity of 200W after a test run with a 1-year stretch:

transformer - close to 70 degrees Celsius, radiator diodes without active blowing - close to 90 degrees Celsius. With active blowing - it is close to the room and practically does not heat up. As a result, the radiator has been replaced, and on the next photo, the living block is already with another radiator.

During the development of the block of life, materials were collected from the site vegalab and radiokot, on the forum "Vega" there were also reports of descriptions of the block of life, so the option of the block from the protection of the short circuit, which is not bad. In my case, for example, with a vipadical short circuit, a path burned on the board near the secondary lance

Respect!

Before turning on the heating block, it vibrates through the lamp, heating up the exhaustion of the troch more than 40W. At the first turn on to the measure, it is guilty for a short hour of burning it out. She's practically not to blame! With this, you can change the voltage and try to lightly turn on the block (no more than 20W!). Everything is fine, - you can clean up the light bulb and start testing it.

Leather car enthusiast maє for 12 V battery. It's not wonderful, even one only power transformer at 200 watts, you can carry up to 5 kg. Therefore, having conceived the choice of a pulse charger for a car battery. On the Internet, more precisely on the Kazus forum, I know the scheme of this memory.

Scheme of the principle of memory - click to increase the size of the world

Zіbrav, work miraculously! Having charged the car battery, having adjusted the charger to 14.8 V and the stream is close to 6 A, it cannot be recharged or undercharged, when the voltage at the battery terminals is 14.8 V, the charging stream drops automatically. So charging a helium lead battery with a PC without interruption is normal. Do not be afraid to flicker at the exit of the charger. And the axis of reversal of polarity needed to be robbed, he himself zrobiv on the relay.

Drukovana fee, data deyakі radioelementi and іnshі files marvel at the forumі.

Zagalom raju yogo robiti, so that this memory has a lot of advantages: small expansions, the base of radio elements is not scarce, you can buy a lot, including a ready-made pulse transformer. Having added yoga to the Internet shops, they sent it cheaply. I’ll change my mind, replace the VD6 Schottky diode (thermal stabilization), putting just a 100 ohm opir, a charger and working with it miraculously! The scheme was selected and tested:Demo.

The circuit of the yakіsnogo charger will be built on the basis of the IR2153 microcircuit, the napіvbridge driver, which is self-acting, as it is often used in electronic ballasts of energy-saving lamps.

Scheme pratsyuє vіd merge zminnoї volta 220 volts, її vihіdna pouznіstі close 250 watts, and tse close 20 amps at 14 volts vihіdnої voltage, which is sufficient for charging car batteries.

At the entrance there is a fringing filter, the intake of voltage drops and re-wiring to the block of life. Thermistor protects the keys for the first hour of the switching on of the circuit up to a minimum of 220 Volts. Then the net voltage is straightened out by a bridge.

Through the intermediate support 47 kOhm, the voltage to pass the generator microcircuit. Singing frequency pulses go to the gates of the high-voltage switches, as if they are transmitting voltage into the winding of the net transformer. On the secondary winding, I may need a voltage to charge the batteries.

The output voltage of the memory is to be determined by the number of turns at the secondary winding and the operating frequency of the generator. Ale, the next frequency is higher than 80kHz, optimally 50-60kHz.

High voltage switches IRF740 and IRF840. By changing the capacity of the capacitors at the input port, you can increase or change the output pressure of the charger, if necessary, you can reach 600 watt pressure. Ale needs 680 microfarad capacitors and a hard diode place.

The transformer can be taken from the computer unit. And you can do yoga yourself. The primary winding should be placed 40 turns on a rod with a diameter of 0.8 mm, then we put a ball of insulation on the winding of the secondary winding - here 3.5-4 turns to add a thick wire or vikoristovuvat rich wiring.

After vipryamlyacha at the circuit of installations, the capacitor, which filters, the capacitance is not more than 2000 microfarads.

At the exit, it is necessary to put a pulse diode with a strum not less than 10-30A, which will immediately light up.

Respect for the memory scheme, there is no sound of a short flicker and it will be right, as it will become.

The diode place is built up with any direct diodes with a strum not less than 2A, it is possible and more and with a turning voltage of 400 Volts, it is possible to vicorate a prepared diode place with an old computer block living in a new turning voltage for 600 Volts.

To ensure the necessary parameters for the life of the microcircuit, it is necessary to take an opir of 45-55 kOhm from a voltage of 2 watts, since you cannot know such ones, add a little low-voltage resistors in series.

An even tighter charger for a car up to 50 Amperes. We have more than once started a language about different chargers for batteries. This time, there will be no blame, we can see a tighter charging attachment, which can be seen to be tighter up to 600 W with the possibility of overclocking up to 1500 W.

I realized that for such high strains you can’t do without an impulse dzherel of life, otherwise the dimensions of such an outbuilding will be incomprehensible masses and expansions. The milking scheme is simple, the little one is shown below.

Robotic principle zagalo does not look at other impulses of life, as we looked at earlier. The structure of the robot is motivated by such a rank, the cob of the thread is filtered, no pulsations are taken in, then they are straightened and fed to the keys, like shaping impulses high frequency vydpovidny schemes cheruvannya them. Then the pulse transformer lowers the voltage to the required value and is rectified by a superb bridge rectifier. Zagalom, and everything is simple.

AT to this particular type the role of the key management scheme is played by the generator, which is set, based on the IR2153 microcircuit. The wiring of the microcircuit is shown in the diagram.

As a key, the IRF740 transistors can be reversed, and it is significantly more significant that the transistors themselves set the load of the charger. With the IRF740 victorious, an output of approximately 850 watts is guaranteed.

At the entrance, there is a filter cream, and a thermistor is also installed for the starting jet exchange. Thermistor must be no more than 5 ohm and strums up to 5 A. at the input of the fencing voltage of 50 Hz, there are no diodes, but there are standard ones: the reverse voltage (at 600 V) and the struma (6-10 A) are few, you can practically take it from the given parameters.

Another place of installation at the exit may have one peculiarity, due to the fact that a high-frequency voltage is supplied from the transformer, to that the turning voltage is not less than 25 V and the turning stream up to 30 A, in the general order it is necessary to take ultra-wide diodes. Before speech, as the first place is not obligatory to vicorate 4 diodes, you can take a ready-made diode collection from the computer block of life.

Be richer at the montage. Electrolytic capacitors, installed after the first bridge, must be charged at a voltage of at least 250 V and a capacity of 470 microfarads can be taken from the computer unit. Everything is simple with a transformer, you can take one from the same computer block of life, which does not need to be rewound.

Power keys are naturally necessary to install heat, because high points in transistors cannot be installed either by different radiators, or by isolation with mica gaskets.

To facilitate repair work, it is necessary to insert a microcircuit into a special case for easy removal and replacement, it is important to facilitate repair and repair. To change the attachment after installation, to increase it in the idle mode, tobto. without pretense. The power keys of different duties are heated in flames. The intensity of 25 ohm resistors on the gates of the field devices is enough to take 0.5 watts.

A resistor, installed according to the life of the IR2153 microcircuit, can be taken in the range of 47 kOhm to 60 kOhm with a cotton wool of at least 5 W, є strumoobzhuvalnym for the microcircuit's strumming. Vihіdnі condensers are guilty but they are connected with a voltage not less than 25 V and a capacity of 1000 microfarads.

I want to remind you that your respect is that the circuit has a short-circuit protection, polarity reversal, a daily indication of the robot is too thin. All these imperfections can be easily corrected, and more stench was described on our resource more than once.

I also want to point out one thing, if you need to repair the car or fill up the air conditioner, then there are no problems. It’s a miracle company, as it is engaged in cym on a professional level and at the same time to work everything for itself.
