Abstract:
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 DC power supply; a second switching device connected to the DC power supply; 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. When the first and second switching devices are turned off, a current flows through the second diode, clamping diode, first inductor and inductive load to completely flow out a current in the first inductor, and then a current flows through the second diode, second inductor and inductive load.
