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.
