Generalized analysis of soft-switching DC-DC converters

In this paper, based on the switching-cell approach, a generalized steady state analysis for families of soft-switching DC-to-DC power converters is presented. Complete generalized design equations are also given. The concept of generalization and a step by step procedure for the generalized process are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, QSW-CC, QSW-CV, ZCT-PWM and ZVT-PWM. Also, it has been noted that all the analyzed families have one generalized transformation table. The basic generalized equations are summarized and a cell-to-cell comparison introduced. It is shown that the generalized analysis leads to several advantages
