Title: Switching power supply circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2001-11-08
Abstract: PROBLEM TO BE SOLVED: To improve power factor and AC-to-DC conversion efficiency, and to reduce ripples. SOLUTION: In a switching frequency control type composite resonance converter, a voltage resonance pulse voltage generated in a primary voltage resonance converter is fed back to two high-speed recovery diodes, to which an insulating converter transformer is connected in series, via the tertiary winding of the transformer for improving the power factor. In this case, the primary winding and the secondary winding of the transformer are connected in series to the respective high-speed recovery diodes. The primary winding and the secondary winding have different polarities and equivalent inductance values. Since the charging current applied to a smoothing means is shunted by a first rectifying circuit, comprising the high-speed recovery diodes and a second rectifying circuit comprising low speed recovery diodes, so that a large current produced in the neighborhood of the peak value of an AC input voltage is not applied to the high-speed recovery diode.
