    Abstract: An electric compressor comprises an electric motor, a filter circuit, a capacitor, an inverter circuit, a drive circuit, a power supply circuit, a switch that connects or disconnects a power supply path that passes power from the power supply circuit to the drive circuit, and a control circuit that controls an operation of the switch. The control circuit connects the power supply path in response to the voltage between the capacitor and the inverter circuit being higher than that between the power supply circuit and the drive circuit, and the control circuit disconnects the power supply path in response to the voltage between the capacitor and the inverter circuit being lower than the voltage between the power supply circuit and the drive circuit.
