In this paper, a generalised approach to the analysis of a class of passively soft-switched PWM DC-DC converters is presented. The circuit cell that gives this class of converters its passively soft-switched characteristics is first introduced. The use of this circuit cell to transform the basic hard switched converters (buck, boost, bucklboost, Cuk's, Sepic and Zeta) into their varied passively soft-switched PWM topologies is illustratively presented. A generalised analysis representative of all the soft-switched converter types in the class is carried out.
