This paper presents a quasi-resonant two-switch flyback converter with input voltage range extension circuit, which allows wider operating input voltage range while maintaining the near zero voltage switching (ZVS) of conventional two-switch quasi-resonant flyback converter. The proposed design consideration is verified with 156 W power supply for all-in-one PC, where the holdup time is extended allowing smaller size of bulk capacitor.
