FIELD: transport.
SUBSTANCE: proposed method comprises the stages that follow. Every switch of charging device is equipped with, at least, one controlled electronic power switch to control power in the arm it is incorporated with. In normal conditions, control unit renders controlled electronic elements conducting or non-conducting for certain intervals for three-phase voltage rectification. Note here that switching frequency for transistors is, at least, twenty times higher that three-phase voltage frequency. Note also that in emergency said control unit control electronic elements for generation of auxiliary three-phase voltage for supply of standby auxiliary consuming hardware.
EFFECT: simplified design, smaller weight and overall dimensions.
