a zero-potential pole-related potential of the primary power source (for connecting its second pole serves terminal 7), terminal 10 for connecting the potential output of the control signal source (for connecting its second output terminal 9). Transistors

I.1-l.tt are connected in series, with the emitter and base of the transistor

I, 1 are connected respectively to terminals 9 and 10, and the collector of transistor 1.P is connected to terminal 6, One of the inputs. the pins of the voltage divider (pin of the resistor 2.1) are connected to the emitter of the transistor, and the output pins to the bases of the rest are transistor. ditch The potential output of the auxiliary low-voltage source 5 of constant voltage and the collector of transistor 1.h through diodes 3 and 4 are connected to another input of the voltage divider (the output of the resistor 2.ts.

The device operates as follows: obsias.

When the voltage across the collector of transistor 1.and exceeds the voltage of the UL of the auxiliary low-voltage source 5, the diode 4 is open, and the diode 3 is closed and prevents the load current from flowing through the source 5. In short, the power from the latter is not consumed. In this mode, a portion of the load current, which flows through, 4, is used to control the 7– 1.1–1 link switches, i.e. A cut voltage divider 2.l-2.h is supplied from the primary power source. If with the opening control signal from the control source

the voltage of the collector of the transistor 1. and becomes less than the voltage Vg of the source 5, the diode 4 is closed and the entire load current begins to flow through the transistors 1.1-1, And. In this case, the diode 3 opens and the control current comes from source 5. Due to this, a further decrease in the voltage on the collector of transistor 1.4 does not lead to a decrease in the voltage on the upper input divider. The control circuit, powered by source 5, allows the transistors to be maintained. 1.1-1.c in the open state up to the saturation mode, ensuring full transfer of voltage to the load 8. 1.1-I.M transistors work; in linear mode due to the simultaneous supply of control current to their base from source 5 through resistors 2.1-2.c divider. Diodes 3,4 allow the source 5 to be disconnected from the primary power supply. The voltage value V of the source 5 can be selected several times less than the voltage Vf, the primary power source, i.e. approximately equal to the value of the residual voltage on the transistors 1,1-G, P, which would be in this circuit without the source 5, Therefore, in the open state of the transistors 1. 1-1. The power consumed by the e-1 ma from the primary power source is as much less than the power allocated to known devices.
