Influence of the Snubbers and Matching Transformer on an Optimal Trajectory Controlled Resonant Transistor DC/DC Converter

Abstract

This work examines a series resonant DC/DC optimal trajectory controlled converter during operation above resonant frequency, taking into account the influence of the snubbers and matching transformer. We obtain expressions for the load characteristics, boundary curves between possible modes and limits of the soft commutation area. Computer simulation and experimental observation confirm the theoretical results.
