FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to voltage supply circuits for providing power to consumers. A voltage supply circuit is proposed to provide power to at least two consumers, wherein one consumer can be activated and deactivated, with voltage connected to mains voltage, wherein there is a filtering device and a rectifier on the consumer side relatively to it. Rectified voltage can be supplied to each consumer by means of decoupling diodes, and one converter with indirect power transmission is connected to one consumer. The specified converter with indirect power transmission generates, by means of a switching device, in particular when switching a transformer of the converter with indirect power transmission, switching voltage that is higher than supply voltage, wherein the specified switching voltage can be supplied to the second consumer by at least one N-MOSFET for activation/deactivation.
EFFECT: improvement of the voltage supply circuit.
