A voltage generating circuit for generating a DC voltage at both ends of a series capacitor based on an AC voltage generated from an AC power supply with one end thereof connected to a coil, the series capacitor including a first capacitor and a second capacitor with a series connecting point thereof connected to the other end of the AC power supply, the voltage generating circuit comprising: a first transistor connected to the one end of the AC power supply via the coil; a second transistor connected to the other end of the AC power supply; a first diode connected in parallel to the second transistor in a reverse direction, and in series to the first transistor in a forward direction; a second diode connected in parallel to the first transistor in a reverse direction, and in series to the second transistor in a forward direction; a third diode connected between the one end of the AC power supply via the coil and one end of the series capacitor, in a forward direction from the AC power supply to the one end of the series capacitor; and a fourth diode connected between the one end of the AC power supply via the coil and the other end of the series capacitor, in a reverse direction from the AC power supply to the other end of the series capacitor.
