Abstract
A motor-driven compressor for a vehicle includes a housing, a compression unit, a motor, and an inverter device. The inverter device includes an inverter circuit, a capacitor, a current sensor, a determination means configured to control switching elements in response to the current sensor not detecting a flow of current when the motor stops operating and configured to determine whether or not the current sensor detects a flow of current when controlling the switching elements, and a discharge starting means configured to start discharging the capacitor when the determination means determines that the flow of current has not been detected.
