Description

one

Known voltage regulators with a constant | 11th voltage contain a parallel regulating transistor, the base circuit of which is connected to the output winding of a magnetic amplifier of a lattice-pulse modulator, which has a working and control windings, a reference voltage source and an LDS filter.

To reduce the weight and size of the filter and increase the efficiency. In the proposed “stabilizer,” the working winding of the magnetic amplifier through the collector junction modulates the Hiero transducer; the resistors and switches are parallel to the source of the reference source;

The drawing is a diagram of the described stabilizer.

The stabilizer consists of an adjustable transistor 1, a BDS filter containing a choke 2, a diode 3 and a capacitor 4, and a phyro-impulse modulator 5. The modulator consists of a magnetic amplifier 6 with a working 11 7 controlling 8, a base 9 of 1mot. kami and feedback winding 10, transistors 1 and 12, a transformer 13 with output windings 14-16, a differentiating capacitor 17 and a setting generator 18. The working winding 7 of the magnetic amplifier 6 is powered by the reference voltage source 19, and the unwinding is the winding 8 - from counter-included sources 19 and 20 o ornogo and input voltages, respectively.

The stabilizer works in the following way.

At the beginning of each period at the base of the transistor 11 from the winding 15 of the transformer 13 through the capacitor 17 receives the opening of the terminals. The operating winding 7 of the amplifier 6 is applied to the reference voltage of the source 19. The transistor 11 is held in an open state by the difference of the voltages of the MOT1KI 10 of the amplifier 6 and the windings 14 of the transformer 13 (the first voltage is greater than the second). At this time, the base of the control transistor 1 from the winding 9 of the amplifier 6 is applied to an unlocking and artery, which keeps it open

as long as the cardiac amplifier is on. After saturating the core of the amplifier 6, the voltage across its winding 10 drops to the pool and transistor II is locked by the voltage of the winding 14 of the transformer 13 to half a period. The control transistor 1 is thus locked by the voltage of the auxiliary switching voltage. During the next half-cycle, all the windings of the transformer 13 irp IJOMOHUI generator 18 change

polarity of science. Through the transistor 12, opened by the voltage of the winding 16 of the transformer 13, the difference between the voltages of the sources 19 and 20 is applied to the correct winding 8 of the amplifier 6. On the winding 9 of the amplifier appears a disconnecting transistor 11. The regulating transistor 1 continues to be in locked state. When changing the input voltage, the time of the open and closed state of the regulating transistor changes, and a parallel stabilization of the output voltage of the stabilizer is performed at a constant ludulation frequency.
