Abstract
A zero-voltage-switching (ZVS) synchronous buck converter with a coupled inductor is proposed. An auxiliary circuit which is incorporated in the conventional synchronous buck converter allows power switches to operate with ZVS. Moreover, the reverse recovery problem associated with the body diode of the synchronous switch is solved. The operating principle and a steady-state analysis of the proposed ZVS synchronous buck converter are presented. Experimental results based on a 115-W prototype are provided to verify the effectiveness and feasibility of the proposed converter.
