摘要：

A power supply circuit comprises a rectifier circuit (2) for converting an AC voltage to a DC voltage, a boost chopper circuit (3) for boosting an output voltage of the rectifier circuit based on a duty ratio signal; a smoothing circuit (4) for smoothing an output voltage of the boost chopper circuit; and a control means (5) for creating the duty ratio signal, the control means (5) is provided with a function for generating a DC voltage ripple information of the smoothing circuit, and correcting or modifying the duty ratio signal based on the DC voltage ripple information.
