Design Oriented Steady State Analysis of Series and Parallel Resonant Converters

Abstract

High efficiency, high power density and high performance DC-DC converters are the need of the hour in electric vehicle, consumer electronics and telecommunications industry. Resonant converters have proved to be very efficient even for high power applications due to their low switching losses. However, their design and control is still a challenging process. This paper presents the steady state analysis and design of series and parallel resonant converters based on fundamental harmonic approximation (FHA) technique and highlights the importance of load dependent properties in the design of resonant converters.
