Abstract
This paper presents a Buck DC-to-DC converter using a novel lossless c ommutation cell for high switching frequency and high power operation. The proposed cell consists of a main and an auxiliary switches, with ZVS and ZCS switching characteristics, respectively. The converter con trol using this cell is realized by the PWM technic, with constant swi tching frequency operation. The complete operation principles, theoret ical analysis, relevant equations, state space phase, simulation and e xperimental results for the Buck converter are presented.
