FIELD: electrical engineering.SUBSTANCE: invention relates to electrical equipment for vehicles with electric traction. Method for starting an electric power converter for electric vehicles is that an input voltage is applied to the filter capacitor through the heater, voltage on the capacitor is monitored and when this voltage reaches a set value the capacitor is connected directly to the network. In this case, the heater is connected to the serial connection circuit between the network and the capacitor. When the voltage reaches a predetermined value on the condenser, the heater is connected to the series circuit with a breaker that is connected in parallel to the condenser. Electric transport car contains a filter capacitor, in parallel to which a DC-to-AC inverter and a circuit of sequential switching of a breaker with a heater are connected.EFFECT: technical result of the invention consists in increasing the reliability of the start-up of the electric power converter.1 cl, 1 dwg
