An electric power conversion apparatus includes: an electric power input terminal; an electric power output terminal; an electric power conversion circuit; a sensor circuit generating a detection voltage corresponding to a voltage at the electric power output terminal; a control circuit operable based on a first power supply voltage, including an input terminal to receive the detection voltage, and controlling operation of the electric power conversion circuit; and a power supply circuit generating the first power supply voltage and a second power supply voltage. The sensor circuit includes: resistors provided in a path coupling the electric power output terminal to a reference node, the resistors being coupled in series via first and second intermediate nodes, the second intermediate node being coupled to the input terminal; and a first diode including an anode coupled to the first intermediate node, and a cathode to be supplied with the second power supply voltage.
