FIELD: electricity.
SUBSTANCE: present invention relates to electrical engineering, namely to the feed circuit (16) of the M-phase synchronous machine (14) comprising: a continuous input current converter (22) into a polyphase alternating current; storage battery (47); device(30) of a short circuit detection before and inside the machine (14); machine (14) isolation device (26) against overvoltage and/or overcurrent of polyphase alternating current; control system (28) of the inverter (22), isolation device (26) and short circuit device (27) made with the possibility to connect the power supply M-outputs (31) with each other.
EFFECT: invention provides an opportunity to reduce the amplitude of the pulse rotational moments and currents generated in case of a short circuit inside the machine.
