A power conversion circuit converting DC electric power into AC electric power and sending the AC power to an inductive load, includes a first switching device connected to the positive pole side of the DC power supply to exhibit a conductive state and an interrupted state of a current; a second switching device connected to the negative pole side of the DC power supply to exhibit a conductive state and an interrupted state of the current; a first inductor provided between the first switching device and the inductive load; a second inductor provided between the second switching device and the inductive load; and a clamping diode connected between a first connection point between the first switching device and the first inductor, and a second connection point between the second switching device and the second inductor. Thus, conduction is provided from the second connection point to the first connection point.
