In this paper, a modified ZVZCS(zero-voltage/ zero-current switching) commutation cell with minimum additional components, which provides soft switching at both turn-on and turn-off of maio and auxiliary switches as well as diodes In PWM converters, is presented The proposed soft-switching technique is suitable for not only minority but also majority carrier semiconductor devices The auxiliary switch of the proposed ZYZCS commutation cell is In parallel with the main switch, and therefore, there IS no current stress on the main switch and diode The operation principles of the proposed ZYZCS commutation cell are theoretically analyzed using the PWM boost converter topology as an example Theoretical analysis, simulation and experimental results verify the validity of the PWM boost converter topology with the proposed ZYZCS commutation cell.
