PROBLEM TO BE SOLVED: To reduce the number of components of a circuit capable of abruptly changing a rising edge and a falling edge of a rectangular-wave-shaped drive current supplied to a switched reluctance motor.SOLUTION: A power conversion device includes: a capacitor having one end connected to a plus side of a DC power supply; a first switching element provided between the other end of the capacitor and one end of a coil; a second switching element provided between the other end of the coil and a minus side of the DC power supply; a third switching element provided between the plus side of the DC power supply and the other end of the capacitor; a first diode having an anode terminal connected to the other end of the coil and a cathode terminal connected to the other end of the capacitor; and a second diode having an anode terminal connected to the minus side of the DC power supply and a cathode terminal connected to the one end of the coil. |
