FIELD: electricity.
SUBSTANCE: positive feedback is introduced between the control transistor and the current amplifier by way of a resistor placement between the control transistor collector and the current amplifier base; the resistor is introduced for direct displacement of the current amplifier base with the control transistor replaced with a transistor conductance whereof is different from the power transistor conductance type. As a result of each blocking generator tripping the circuit is disconnected and all the elements are de-energised. Comparative evaluation has shown that at low load currents the current consumed decreases by several orders and is equal to 10 mcA.
EFFECT: voltage converter input current decrease at fixed power output.
