Abstract
A discharge control device performs discharging of a capacitor, in a state in which a battery is not connected to an inverter that drives a motor, by causing electric charges accumulated in the capacitor connected to the inverter to be consumed by windings of the motor. The discharge control device performs the discharging of the capacitor by sequentially generating command values for voltages applied to a α axis and a β axis while causing a voltage phase in an αβ stationary coordinate system having a rotation axis of a rotor of the motor as an origin and defined by the α axis and the β axis orthogonal to each other to be inverted in a predefined period.
