FIELD: transport.
SUBSTANCE: invention relates to electrical engineering and can be used in electrically driven vehicle to allow electric power transfer between power accumulator and power supply or electrical load arrange outside said vehicle. In charge/discharge conditions, inverter (10, 20) converts electric power between electric power accumulator (B) and common-purpose power supply (92) connected to neutral point (N1, N2) via power line (ACL1, ACL2). In charge/discharge conditions, electronic control unit (ECU) (30) sets carrier frequency of inverter (10, 20) equal to that exceeding frequency in motion conditions. Additionally, in charge/discharge conditions, control circuit (40) excited inverter (10, 20) with the help of gate resistance exceeding that in motion conditions.
EFFECT: allowance of noise generated by inverter in electric power transfer between power supply or outside electric load and outside electric power accumulator.
