An electric vehicle controller 50 includes an inverter 11 that drives a motor 12 by receiving power supplied from an overhead line 1, a brake chopper circuit 8 that includes a switching device 6 and a braking resistor 7 and is connected in parallel with the inverter 11, a voltage detector 9 that detects a bus voltage applied to DC buses 4a and 4b, and a control unit 13 that performs power consumption control of causing the braking resistor 7 to consume regenerative power supplied from the motor 12 and overvoltage suppression control of suppressing the bus voltage from being excessive. The control unit 13 controls the switching device 7 such that a second duty ratio used at the time of performing the overvoltage suppression control is lower than a first duty ratio used at the time of performing the power consumption control.
