| Abstract |
This paper presents a Buck DC-to-DC converter using a novel lossless commutation 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 control using this cell is realized by the PWM technic, with constant switching frequency operation. The complete operation principles, theoretical analysis, relevant equations, state space phase, simulation and experimental results for the Buck converter are presented. |
