Clamp mode zero-voltage-switched multi-resonant converters

Abstract

A method for improving the performance of zero-voltage-switched multiresonant power converters (ZVS MRCs) is proposed, based on clamping the drain-to-source voltage of the power switch using a soft switching nondissipative active clamp network. Complete DC analysis and design guidelines for the clamp-mode forward ZVS-MRC are presented. Device is shown to perform significantly better than forward ZVS-MRCs without an active clamp.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
