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.

Abstract: A motor-driven compressor for a vehicle includes a control device and a detection circuit. The detection circuit includes an AD conversion circuit. The AD conversion circuit converts an on-voltage from an analog signal to a digital signal. The control device is configured to determine that a battery is in an overvoltage state and stop the motor-driven compressor for the vehicle when a value of the on-voltage detected from the digital signal is larger than an overvoltage determination threshold value.

Abstract: An inverter includes a bus bar as a wiring and a ferrite core that covers the bus bar to absorb electromagnetic noise from the bus bar. The bus bar and ferrite core are integrated by mold forming using a resin material in a state of exposing a part of the ferrite core.
