Abstract: PURPOSE:To enable to smoothly start an electric railcar even if the railcar moves backward by acting a brake power to the railcar while continuing the supply of electric power from an inverter to an induction motor when a backward movement is detected at the starting time of the railcar. CONSTITUTION:When an electric railcar moves backward so that an induction motor 7 rotates reversely to a forward command or a backward command in case that a power drive command is delivered, a backward detector 11 detects it and produces an output. A brake command is outputted from a brake power controller 12 to brake the railcar from moving backward.
