Abstract
A resonant capacitor and an inductor are connected in series between a primary winding of a transformer and a second switching element. A first rectifying and smoothing circuit including a first rectifier switching element and a capacitor rectifies and smoothes a voltage generated in a first secondary winding of the transformer, and takes out a first output voltage. A second rectifying and smoothing circuit including a second rectifier switching element and a capacitor rectifies and smoothes a voltage generated in a second secondary winding of the transformer, and takes out a second output voltage. A control circuit controls an on-time of a first switching element and an on-time of the second switching element in accordance with the first output voltage and the second output voltage, respectively.
