Beschreibung
Zusammenfassung:	A control circuit (14) performs at least pulse width modulation control on a first leg (500) and selects to perform pulse width modulation control and pulse frequency modulation control, to perform pulse width modulation control and phase shift modulation control, or to perform pulse width modulation control, pulse frequency modulation control, and phase shift modulation control on a second leg (600), based on comparison of a voltage conversion ratio between DC voltage of a DC capacitor (4) and output voltage to a load with at least one threshold.
