Abstract: A controller switches between modes each having a different connection state of a DC power supply and the capacitor with respect to first and second output points by controlling switches. A generation unit generates a reference wave including at least one carrier wave. The modes are classified into a sustaining mode in which no current is caused to flow to the capacitor, a charging mode in which a current is caused to flow to the capacitor, and a discharging mode in which a current in a direction opposite to that in the charging mode is caused to flow to the capacitor. The controller switches between the sustaining mode and a charging or discharging mode according to the comparison result between a signal wave and the reference wave.

Abstract: A first conversion circuit is electrically connected between a reference potential point and a first input point on a high potential side of a direct current power supply. A second conversion circuit is electrically connected between the reference potential point and a second input point on a low potential side of the direct current power supply. A voltage-regulating circuit is configured to adjust a magnitude of an applied voltage to the first conversion circuit and the second conversion circuit. The voltage-regulating circuit is configured to increase the magnitude of the applied voltage over time during a start time period from a start of supplying power from the direct current power supply until a first capacitor and a second capacitor are charged to a specified voltage.
