Characteristics of the attachment

Devices designated for batteries are divided into several types - transformer and pulse.

• Transformer chargers for car batteries are of great size and size, due to which their voltage coefficient is significantly lower than that of other devices.
• In the end, who will drink on such exercises has gradually decreased.
• Today, the pulse charging device is the most popular type.
• Device and principle of operation
• Any pulse charging device for a car battery is a device used to renew the charge.

Structurally, the pulse memory consists of the following elements: transformer (pulse); straightening device;

stabilizer attachment;

• indicator elements;
• the main unit assigned to control the charge procedure.
• It is necessary to note that all the elements that make up the pulse charging device are small in size due to their design, which is comparable to transformer chargers.

In principle, it is not so difficult to create such a device for charging a car battery with your own hands - for which you will need a board such as a ceramic transistor. As a result of the fact that the design this type

If there is no problem with the method of tension during steady flow, then this option is not the most optimal.

All this means that when quickly charging the battery, which is removed after the influx of steady flow, the plates of the device can simply get wet. And it’s already impossible to renew them. The combined battery charging option is one of the most sparing. When frozen this method

go through from the beginning

steady stream

, and finally the wine procedure begins to change.

1. Then this parameter is gradually reduced to zero, thus stabilizing the voltage level.
2. According to the experts, this robot scheme allows you to avoid or reduce to a minimum the possibility of boiling the car battery.

In addition, this approach also reduces the availability of gases.

Aspects of property selection

1. If you want to ensure that your car battery functions properly, you need to think ahead about purchasing the necessary charger for charging. And the songs of the nuances of this diet, which is important to believe: Before many people, we need to supply power - if possible, the charger, working according to its circuit, will renew a completely discharged car battery.
2. Here you need to be aware that not all charging devices sold in stores can meet such requirements.
3. An hour to charge the car battery.

Due to the fact that there are no indicators on the charger, you can understand that if the battery is automatically charged, you can use the indicator to indicate the value of the charge.

However, since this parameter cannot be changed for three years, please make sure that the battery is charged.

Never charge the device for more than 24 years, as this will cause the electrolyte to simply boil and cause a short circuit in the middle of the circuit. Instructions for making a pulse charger with your own hands To create a charger for a car battery with your own hands, use the IR2153 circuit.

This circuit differs from the circuits for generating a primary charger in that instead of two capacitors connected to the middle point, only one electrolyte is used.

Varto note that

a diagram is given

The filter does not need to be added to the circuit, but instead, you need to install a number of containers and the throttle itself. To reduce the amount of waste at the input to the element that is being filtered, it is necessary to add a 5 Ohm thermistor to the circuit. This element can be drawn with your own hands from the PC life block.

Important moment

if an electrolytic capacitor is installed.

This must be selected, relying on a special ratio of 1 Watt - 1 µF, the voltage level should become 400 volts. Due to its design, such a scheme is guaranteed to be downtime. In fact, if you approach this food correctly, then it won’t be so difficult to argue, since you don’t have enough information.

And for doctors, if you have material with all the necessary diagrams and instructions at your fingertips, it will be easy to deal with such tasks.

It is clear that you cannot separate the transformer from the resistor, rather than just go to the store and buy the required charging device.

All the nuances that need to be explained, as well as detailed

Pokrov's instructions

High-voltage switches IRF740 and IRF840.

The variable capacity of the capacitors at the input lancus can be increased or the output voltage of the charging device can be changed, if necessary, the voltage can reach 600 watts.

All you need are capacitors of 680 µF and a tight voltage.

The transformer can be taken from the computer unit.

And you can earn it yourself.

After rectifying the installation circuit, the capacitor that filters has a capacity of no more than 2000 uF.

At the output, it is necessary to install pulsed diodes with a flow rate of at least 10-30A, otherwise it will immediately burn out.

Thankfully, the charger circuit is not immune to short circuits and will immediately come out fine if that happens.

Another version of the charging device circuit based on the IR2153 microcircuit

This place consists of any direct diodes with a current of at least 2A, perhaps more with a return voltage of 400 Volts, you can use a ready-made one with an old computer unit living in The return voltage is 600 Volts at 6A.

• To ensure the necessary parameters for the life of microcircuits, it is necessary to take a reference of 45-55 kOhm with a voltage of 2 watts, since you cannot find such ones, connect a series of low-voltage resistors.
• Butt of a pulse charger for a car battery
• Many car owners are familiar with the situation when the smell behind the kermo indicates that the battery does not have enough charge to start the engine.

In such a situation, you will have to think about charging the car battery. Therefore, you will always need to have a charging device for your car battery on hand.. When starting and starting-charging models, they must be connected until the moment the engine starts. I want it

portable chargers

Because they keep their batteries in the middle, they start the engine using their energy. You can easily take these portable chargers with you on the go. If you have a garage with electrical connections, then you should buy a starter-charging device.

In this case, if necessary, you can start the engine when the battery is installed.

And if the battery charger is only used for charging the battery, then take a simple model without special options.

According to the design, the charging devices are divided into pulse and transformer ones. The stock of transformer models includes a rectifier (one place) and a step-down transformer. In the design of inverter charging, the inverter operates and a short-circuit protection is transmitted.

Models based on a transformer are larger in size.

• Zvichainy koristuvachevi
• It is recommended to choose pulse charging, which is more convenient, compact and lightweight.

How does the device work?

The edge filter C1, C2, C3, L1 is supplied with a voltage of 220 volts from the household electrical circuit.

The role of the filter is to block the transfer of power from the power supply.

Next, the voltage is verified on the diodes VD1, VD2, VD3, VD4 and smoothed with the help of capacitor C5.

The role of resistor R3 is to circulate the charging of capacitor C5.

The discharge goes up to the voltage on the battery up to 10.5 volts until the comparator R20, R21, DA1 is requested.

After this, output DA1 is set to 1 again and the charging cycle begins.

When the battery voltage reaches 14.2 volts, the comparator R11, R14, DA1 is used. Unfortunately, if the SA3 switch is set to the “Disposable” position, the HL2 LED goes out and the device loses its charge. Once SA3 is installed in Bagatorazovo, a new cycle will be launched and a discharge will occur.

Capacitors C6, C7 protect the circuit during the transition and slow down the operation of the comparators during the transition from one mode to another.

• The DA3 stabilizer protects microcircuits during short-term contact on the battery terminals, and in idle mode the voltage at the output of the converter jumps to 25 volts.
• Researchers believe that there may be a need for further regulation of threshold comparators.
• To avoid this, avoid switching on the HL1, HL3 light bulbs.
• Then until

adjustable block

The life is connected to terminals X1 and X2.

Diodes VD13 and VD14 are upgraded to type KD213A(B).

The authors of the circuits recommend replacing them with Schottky diodes of type KD2997A and KD2999A.

• The VD12 diode is rated at 2-3 amperes (30 kHz) and the voltage is 600-800 volts.
• Optocouplers U1 and U2 are upgraded to type AOT127.
• Their insulation voltage is no less than 500 volts.
• It appears that KT315 can be replaced by either KT312 or KT3102, rated at 30 volts.
• VT3 is upgraded to type KT801 A(B).

VT7 tse type KT819 A (B, C).

Capacitors on the circuit:

C2 can be replaced with an electrolytic one;

C1, C19, C22 - type K78-2;

C3, C4 – type K15-5, voltage less than 600 U;

C5 - capacity 220 µF, 400 V. Or two 100 µF, 400 volts (type K50-32);

Other capacitors on the circuit are upgraded to type K50-35. To change the size and weight of the charger, the authors of the circuits implement a cooling circuit with a small M1 fan. The diagram is shown below.

The circuit diagram of such a pulse block for living on the Internet tends to be completed often, but in some of them there is a compromise, I, in my opinion, have finalized the circuit a little.

The driving part (pulse generator) of the data collected on the PWM controller IR2153.
The circuit is a typical on-bridge inverter with a power of 250 watts.

Pulse charger for charging batteries

The power of the inverter can be increased to 400 W by replacing the electrolytic capacitors with 470 uF 200 Volts.

Power switches with voltages up to 30 -50 W are left cold, otherwise they need to be installed on heat dissipation, as there may be a need for air cooling.

Vikoristano is a ready-made transformer for the computer block of life (literally whatever).
They run a 12 Volt bus up to 10 Amperes (keep in the tightness of the block in which they were installed, in some cases the winding is 20 Amperes).

The 10 Amp power supply can be completely removed to charge high-pressure acid batteries with a capacity of up to 200A/year.

One straightening machine - my socket was vikoristan more tightly than a single folded 30 Amp schottka.

There is only one diode.

UVAGA!
Do not shorten the secondary winding of the transformer, which will lead to a sharp shift in the primary winding, leading to overheating of the transistors, as a result of which smells can get out of order.

The throttle is also removed from the pulse power supply, which can be switched off in the circuit, but there is no problem with the edge filter. for 12 V batteries. All old chargers perform and complete their functions with varying degrees of success, but they also have a problem - they are too large in size and capacity. It’s not surprising, even just one power transformer

at 200 watts you can load up to 5 kg.

That's why I decided to get a pulse charger for my car battery.

On the Internet, more precisely on the Kazus forum, you know the diagram of this memory.
