FIELD: transport.

SUBSTANCE: invention relates to electrical traction systems of vehicles. Electrical power control unit comprises a DC / DC down converter and a boost converter. And the boost converter contains a choke and a capacitor. Choke and the DC / DC down converter are fixed to the body of the on-board device, and the choke and the DC / DC down converter are stacked one on top of the other. Capacitor is located near the choke or DC / DC down converter in relation to the direction, in which the choke and the DC / DC down converter are stacked one on top of the other. Capacitor and the DC / DC down convertor or choke are attached to each other via a bus, wherein the bus is configured to electrically connect a capacitor lead to the output of the DC / DC down convertor or choke. Control unit converts the DC power into AC power and provides the converted power to the motor. Electrical power control unit is fixed inside the body of the on-board device.

EFFECT: technical result consists in reliable fastening of elements in the control unit.
