Abstract :
This paper presents a novel soft-commutation cell capable of providing ZCS operation keeping the main switch current equal to the load current. The operation and main properties of this cell are also included. A theoretical approach for the design of the proposed cell applied to a DC-DC Buck converter is presented and corroborated by simulation and experimental results of an 800 W laboratory prototype.
