Schemes of voltage stabilizers. Regulovane zherelo zhivlennya iz strumu strumu Voltage stabilizer with strumovy strumu

A simple circuit, with average parameters, based on transistors with great powers. The bula is crushed for its needs like a laboratory.
Often I had to deal with repairs or the launch of various schemes, for which it was necessary just to keep them alive 3V, 5V, 6V, 9V, 12V ... At the head there were blocks of life such as calculators, tape recorders, accumulators, batteries. Sometimes it was quiet, that in the middle of the day the dzherelo did not give great strums, in such a rank ryatuyuchi less in the face of the wicket. Zvichayno robbing one-two-transistor stabilizers to solve this problem, but the results were not satisfied. Here, on another whil of inspiration, those with whom I want to share have been born.
Check the dossi when repairing and launching the outbuildings, so it’s necessary to change the voltage significantly. And also in case of an unexpected zastosuvanni - re-verification of stabilitrons, charging of finger-type batteries, just like a stable stream. In such situations, the obviousness of wanting a voltmeter at the exit is already obvious.

Scheme

Also, X1 is supplied with a minus voltage, and X2 is taken stabilized and surrounded by a free stream of voltage. In short, VT3 is a control, VT4 is a comparator and a signal for the break of the voltage stabilizer, VT1 is a comparator and a signal for the break of the stabilizer of the outgoing stream, VT2 is a sensor for the presence of an exchange of an outgoing stream. The expansion of the voltage stabilizer option was taken as the basis.

It has been slightly changed, so that you can change the voltage at the largest possible distances, and remove the blocking of the stabilizer. Addendum R8, to enable the robot to exchange the external stream at VT1. Additions R7 and VD3 for setting between the change of output voltage. Capacitors C1 and C2 will help to reduce the ripple at the output.

Now let me go through the explanations on another stake (div. pershu scheme). When a negative constant voltage appears at the input of X1 in the range of 9 ... A stable voltage appears on the stabilizer VD1. Part of the voltage is applied to the VT4 base, which is the result. Yogo strum collector v_dkrє VT3. Strum collector VT3 charge C2, and through the dilnik R9, R10 part of the voltage C2 (it’s out) is on the VT4 emitter. This fact does not allow the external voltage to increase more, lower subwar (Vbasi VT4 - 0.6V). The answer to that, dіlnik R9, R10 for two. Since the voltage is stable on the basis of VT4, the output will also be stable. Ce working mode. Transistors VT1, VT2 are closed and do not burn.

Let's get excited. Z'appear strum navantazhennya. V_n flow along the lance R2, E-K VT3 and farther ahead. R2 works as a strum sensor. In proportion to the stream, the voltage settles on the new one. The voltage is mixed with a part of the voltage taken for the help of R5 and VD2 and is added to the basic transition VT1 (R3 is purely for the exchange of the base of the VT1 when throwing and defending in such a rank of VT1) and if it becomes sufficient for the output of the VT1, apply to enter the exchange mode external struma. Part of the stream of the VT4 collector, which earlier reached the VT3 base, immediately passes through the VT2 base-emitter transition to the VT1 collector.
Due to the great coefficient of transistor strength, the voltage of the base-emitter VT1 is approximately 0.6V. Tse means that the voltage on R2 will be constant, so the strum through the new one, and then through the tension. The engine R5 can be used to select the strum water from the minimum to the maximum 3A.
In order to show the mode of submerging the strum of water and VT2, ignite the light HL1 with your strum of the collector of wines. It should be understood that the exchange of the struma is a priority over the “stability” of the external voltage.

At the exit, I’ll put a voltmeter, and if the axis is needed on the strum stream, I’ll just quickly leave the tester in the ammeter mode and, for the help of R5, I’ll try the bag.

Details

VD2 and VD3 are 0.6V voltage plugs. You can use other silicon diodes. R4 - deshcho zsuvaє threshold, if you are sleeping light. If wine is burning, it means that there is a place for the depletion of the outer stream. R1 simply surrounds the stream of light. Potentiometry is possible with a larger nominal value (at 2...3 times). R8 can be changed (here up to 4k), so the VT3 transistor cannot be pulled stronger.

With a handed payment - as if in simple schemes, which are prepared in a single copy. There was a board for another regulated voltage stabilizer, the parameters of which were not controlled. Vaughn was turned into a mock-up and a scheme was given on it. Resistors vikoristanі 0.25 W (possible і 0.125) - I don’t know much about it. At 3A (as your vipryamlyach їх give) - the factory rattle R2 (2 W-a) will be set harder (5W) between and varto. Electricity - K50-16 at 16V.

There is no such thing as a folded transistor - "fold" it for some reason. Correct from KT817 + KT315, with letters “B” and dal. (However, I still can’t get stronger at VT3, I would change R9 and R10 to 200 Ohm and R8 to 2 kOhm).

Transformer, rectifier and filter capacitor - Vashі. The stench is not less important, but I would like to tell you about such a larger-less universal stabilizer. (I have a 10-watt trans at 10V / 1A replaceable, the stars of taking blocking places at 1A, and 4000uF / 16V electrofilter. It's disgraceful, then everything fits into the case.

It is necessary to note that the arrow indicator (there are no indications in the scheme) for an additional switch, you can use it as a voltmeter and as an ammeter. In the first one, the bachimo will lose the strain, in the other, the strum will go out.

Together

The case, which can be seen in the photograph, is not much more than that, to repeat it. And in a flash: everything was conceived there, like a mirror image, but having bent the front panel in the wrong way. I'm roztroїvsya and not becoming yoga nіyak embellish.

Filey

Depending on the value of the KKD, the efficiency of the work of the stabilizer - which is more, better. For other models, the parameter changes from 80 to 90% in the range. The most powerful KKD for electromechanical models and reaches 97%. For a small energy supply, the stink of the building will help the work of the workers with a high total exhaustion.

Dimensions and installation type

More stabilizers are insured for installation for sub-logs, as massive models may have dimensions greater than 1 m in length and width. Small pobutovі outbuildings can creak up to the wall. The stench of a thin body, the tovshchina of some kind, ring out, become more than 8 - 10 divs.

Design features

When buying a stabilizer, pay attention to the class protection from the water. As there is no risk of exposure to water, you can attach a model to a non-pressurized case (IP20). If it is possible to get water, choose stabilizers for water protection (from IP21 to IP24). If the attachment is transferred to the vicorist on the street or in the premises, which is not singed, choose a stabilizer in the climatic environment - the building is exposed to minus temperatures. Models for installation in opiate applications are covered for work only for positive temperatures.
Since the vicorist stabilizer can last for a long time, you need a cooling system. The most effective is primus ventilation to the body. With her, such an attachment cannot be turned on through overheating. For rich models, passive cooling is true, if the possession is rented out for short-hour working cycles.

Control and monitoring systems

Stabilizer for controlling the voltage at the input and output, its value is displayed on the panel, where there is a mechanical or electronic voltmeter.
The automatic switch-on system is activated in case of a voltage threat, overheating or a short flicker. Vaughn will prevent stabilizer breakdowns and connections to new accessories.
On the panel, there are also two light indicators - the inclusion of that warning about pardons. Models with a built-in microprocessor provide constant control of the working parameters of the device, and the connected input.

Dovidkova article, which is based on the expert opinion of the author.

The proponation stabilizer may be a rozdilny zahist in vіd navantazhennya along the stream and short circuit. In case of a short circuit at the output of the stabilizer, the spratsovuє vuzol VT3 shield (Fig. 1). When rewound with a strum, spratsovuє zahist on VS1 and K1.

Fig.1. Scheme of the voltage stabilizer

Vuzol electronic zakhistu spratsovuє, if strum navantazhennya create a voltage drop on the resistor R6, it is enough to turn off the thyristor VS1, then. if the voltage difference between the electric electrode and the thyristor cathode reaches approximately 1 V. The voltage pulse through the VD3 diode, which is due to this, should be placed on the base of the VT3 transistor and practically close the curve, and then, the regulating transistor VT1. At the same time, the VD3 diode protects the VT3 transistor from the radiation from the first base of the positive voltage from the anode thyristor band.

However, the electronic system still does not protect the transistor VT1 from thermal breakdown with an excess strum, especially as the transistor is already connected to the robotic process, otherwise the SB1 button was not pressed for a three-hour period.

To prevent the thermal breakdown of the transistor VT1 and serve as an electromagnetic system, it will spratsovuє after a spratsovuє in a few milliseconds (to lie in the relay K1, which vikoristovuєtsya) after that, like a thyristor VS1 vіdkriєtsya. Todi spratsovuє relay K1. The contacts K1.1 switch on the base VT3 to the minus conductor of the live alarm, and the contacts K1.2 turn on the LED HL2 signaling device for protection. If you have found a reason for wanting to do it, press the SB1 button to activate the extra mode of operation of the living block, without switching on attachments to the mesh.

At the input of the stabilizer, a constant voltage of 40 V is supplied. The stabilized voltage of 3 to 30 V is set by resistor R2. The maximum voltage strum is 2 A. The voltage strum is controlled by the PA1 head by switching SA1.

Details of the stabilizer are mounted on a plate made of foil-coated cloth (Fig. 2 and 3) and on the front panel of the housing of the living unit. Regulating transistor VT1 for thermal installations. Transistor KT825 can be replaced by KT825B, G; QT818V, R, WM, GM; KT814G - on KT814V, B; KT816B, V, R; KT315V - on KT315G, D, E.

Thyristor KU202K is replaced by KU201V...KU201L, KU202V...KU202N. The replacement of the diode D220A (VD2) should be D219, D220, D223, KD102, KD103 with any letter indexes, and the replacement of the diode KD105B (VD3, VD4, VD5) - KD106A or be the other silicon with a direct strum.

Change resistor R2 - be it of a type with characteristic A. Relay K1 - REM48A (passport RS4.590.206) or else with two groups of contacts, which intersect, work when the voltage is not more than 30 V.

Resistor R6 has a few turns of constantan, nichrome or manganese wire wound around the body of the MLT-1 resistor. Yogo opіr depends on the value of the spratsovuvannya, which, by its own strength, lie in the voltage on the thyristor’s electric current, with which fault it is blown. So, for example, for the maximum strum, the spratsovuvannya will take 2 A, and the thyristor will turn on when the voltage on the electrode that controls is close to 1 V, the resistor R6 can be used (for Ohm's law) close to 0.5 Ohm. It is possible to install resistors of type C5-16 in case of tension.

More precisely, the resistance of the resistor is selected to be selected between spratsovuvannya zakhist in this order. Before the output of the stabilizer, an ammeter and a variable resistor with a support of 25 ... 30 Ohm are connected in series. At the input of the stabilizer, apply a variable voltage to the direct voltage, and install a voltage of 10 ... 15 V at the output with resistor R2.

In radioamator practice, it is not necessary to provide, if there is a change in strums of a smaller value, for example, 50 or 100 mA, to protect not only the voltage stabilizer itself, but also to live in the new. With this bazhano mother stepinchast, the system zakhistu, vikonan, for example, according to the scheme, induced in fig. Here, the resistor R6.1 is the first stage, the minimum surge is 50 mA, the stabilizer is switched on permanently, and in parallel with it, SA2 is switched by resistors R6.2 ... R6.5 of the lower stages: 100 mA, 500 mA, 1 A 2 BUT.

Designated on the scheme support resistors - orientation. More precisely, it is possible to decompose only knowing the voltage of the thyristor winding, which is used in stabilizers. You can vimirati tsyu prugu so. Install the motor of the changeable resistor R2 at the lowest (behind the circuit) position and connect it to the new electric thyristor electrode, connecting it to the right (behind the circuit) output of the resistor R6.1. Let's increase the liveliness and increase the voltage on the electric thyristor with resistor R2. At the moment when the thyristor is turned on, about which the light diode will signal, measure the voltage with a voltmeter.

Resistors R6.2...R6.5 are mounted directly on the SA2 jumper contacts. Resistors RS1 and R12 are selected without intermediary for the use of the necessary countermeasures.

This voltage stabilizer is intended for the living of radioamator constructions in the process of their adjustment. Vin viroblyaet permanently stabilized voltage vіd 0 to 25.5V, you can change it by 0.1V. Strum spratsovuvannya zahistu vіd navantazhennya can be smoothly changed vіd 0.2 to 2A.

The wiring diagram is shown in Fig. 1. DD2 DD3 switches form a digital code for the output voltage. The digital-to-analog converter on precision resistors converts the lichnik code into a step-up voltage.

Also, the stabilizer may have an indicator (Fig. 3) on the PROM K573RF2.

The adjustment of the stabilizer is adjusted in R26 so that the maximum output voltage reaches 25.5V.
