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: This power transfer device is provided with an alternating current power supply, primary-side coil, control unit, control power supply, and switch. The alternating current power supply has a first converter that converts external power into first direct current power and a second converter that outputs power by converting direct current power into alternating current power at a predetermined frequency. The second converter outputs, as alternating current power, first alternating current power in the cases where the first direct current power is inputted from the first converter, and outputs, as alternating current power, a second alternating current power having a power value smaller than that of the first alternating current power in the cases where second direct current power is inputted from the control power supply.
