FIELD: electricity.
SUBSTANCE: present invention relates to electrically operated machine. The electrically operated machine comprises the engine and the power circuit operating the engine by means of the electric power from the power supply. The power circuit includes the voltage conversion unit converting the input voltage supplied according to the power supply voltage for generation of output voltage and supply of the developed output voltage to the engine, and the current registration unit generating the first signal according to the current flowing through the engine. The voltage conversion unit reduces the size of generated new output voltage when the current registration unit generates the first signal. The voltage conversion unit is designed with a possibility of conversion of input voltage from the power supply for generation of pre-set output voltage which is an input voltage of the engine and exceeding the output voltage of the power supply.
EFFECT: improvement of reliability of the power circuit and the engine.
