摘要：
An isolated interleaved buck type converter is derived by adding a third winding of the coupled inductor to each phase of the interleaved flyback converter. The existing switches of the derived flyback-buck converter can serve as clamp switches to absorb leakage energy and to limit voltage stress on the switches. Only two switches are employed in the proposed converter instead of four switches in the conventional active clamp interleaved flyback converter. Experimental results verified the theoretical analysis and the effectiveness of the presented converter.
