FIELD: electricity.
SUBSTANCE: invention relates to the conversion and distribution of electric power and can be used to power the gas discharge counters. This technical result is achieved by the introduction of a voltage converter amplifier current of timing RC-circuit, an additional transistor switch and the locking of the diode. Zener unlike the prototype device is not connected to the output capacitance and to the output winding of the transformer. If the device prototype pause in the blocking oscillator determines the threshold current of the zener diode and is not more than 1 second, then the claimed invention is defined by a pause of timing RC-circuit and can reach several tens of seconds. Comparative evaluation showed that at low load currents current consumption decreased by order and amounted to 1.0 mcA. Claimed invention can be used in dosimetry equipment for high voltage used in the gas-discharge Geiger-Muller.
EFFECT: technical result achieved in the claimed invention is to reduce the input current of the voltage converter in the absence of external load.
