Abstract
In a DC power supply circuit, a first period and a second period are alternately repeated a plurality of times during each half cycle of AC supplied to the DC power supply circuit. The first period is a period during which current flows along a first current path extending from an output terminal at a high-potential side of a rectifier circuit to an output terminal at a low-potential side of the rectifier circuit, via an inductor and a switching element. The second period is a period during which current flows along a second current path extending from the output terminal at the high-potential side of the rectifier circuit to the output terminal at the low-potential side of the rectifier circuit, via the inductor, a charging current supply path, and a capacitor.
