Abstract

This paper presents a zero-voltage-switching (ZVS) boost converter using a coupled inductor. It utilizes an additional winding to the boost inductor and an auxiliary diode. The ZVS characteristic of the proposed converter reduces the switching losses of the active power switches and raises the power conversion efficiency. The principle of operation and a system analysis are presented. The theoretical analysis and performance of the proposed converter were verified with a 100W experimental prototype operating at a 107 kHz switching frequency.
