Abstract
A zero voltage switching (ZVS) forward converter topology is presented in this paper. In this topology, an auxiliary circuit is employed. ZVS is achieved on both the main and auxiliary switches. The power transformer in the proposed topology is self-reset without the use of a conventional tertiary reset winding. Analysis and design of the circuit are presented. Experiments on a 5 V, 100 W prototype converter switched at a frequency of 200 kHz verify the design and show an overall efficiency of about 90%
