Active clamp ZVS-PWM forward converter

Abstract

This chapter studies the Active Clamp ZVS-PWM Forward Converter. After the presentation of the power converter topology, the qualitative analysis is presented, which includes the description of operation, topological states for each time interval and relevant waveforms. Then, quantitative analysis, focusing on static gain and soft-commutation are presented. The necessary equations for the design of the parameters involved in the soft-commutation are obtained. Also included are numerical examples to illustrate the theoretical analysis, proposed exercises with solutions and numerical simulations.
