Abstract
An electric vehicle control device comprises: a smoothing capacitor to be charged from a DC power supply via a charging resistor; an inverter converting a DC power having been charged in the smoothing capacitor to an AC power to supply it to a load; and a discharging switch causing a voltage having been charged in the smoothing capacitor to discharge via a discharging resistor, and in which a resistor is used as both charging resistor and discharging resistor to simplify a circuit arrangement. In the electric vehicle control device, there are provided a main switch inserted into a main circuit to which a DC power is supplied from the DC power supply, and an auxiliary switch that is connected in parallel to the discharging switch, and is in inverted switching states with respect to the main switch.
