Abstract

This paper presents a Sepic DC-DC converter using a novel lossless commutation cell for high switching frequency and high power operation. The proposed cell consists of one main and one auxiliary switch, with ZVS and ZCS switching characteristics, respectively. The most important property of this cell is the ability to regulate output power and voltage by pulse-width-modulation (PWM), with constant operating frequency, without load limitation and without sacrificing the lossless commutation. A first analysis of the operating principles, relevant equations, state space phase and simulation results for a specific case of the converter, are presented. These procedures will be validated by a prototype laboratory implementation
