Abstract
This paper presents a buck DC-to-DC power converter using a novel lossless commutation cell for high switching frequency and high power operation. The proposed cell consists of main and auxiliary switches, with ZVS and ZCS switching characteristics, respectively. Converter control using this cell is realized by PWM with constant switching frequency operation. Operation principles, theoretical analysis, relevant equations, state space phase, simulation and experimental results for the buck converter are presented
