The flyback converters are widely used in DC-DC power supplies in the small power areas because of its simple structure and robust characteristics. The multiple output and cost effective design makes the flyback converter attractive. The major disadvantage of flyback converter is the hard switching operation which results in a high switching loss, high EMI noise, and high switch voltage stress. To overcome these drawbacks, various kinds of soft switching techniques have been proposed. This paper presents an interleaved flyback converter, which is remarked with ZVS (Zero Voltage Switched) active switches and reduced reverse-recovery loss on the rectifying diodes. This converter can provide up to 500W power with the highest efficiency as high as 91%. In addition, burst-mode control is provided to drive the converter at low load.
