Unified analysis of synchronous commutations in switching converters

The analysis of synchronous commutations in switching converters is discussed in this paper. The Compensation Theorem (CT) is applied in order to define two matrices, called respectively zero-order and first-order master-slave connection matrix (Z-MSCM, F-MSCM), which allow a unified analysis of both hard and soft synchronous commutations in switching converters. The Z-MSCM and F-MSCM provide the analytical basis for studying the interactions among switching devices in any type of switching converter. The method is presented in its general formulation, valid for the analysis of switching converters including feedback circuitry and soft-switching cells. The examples presented show that the CT-based analysis of commutations is a useful and efficient tool for the comprehension of the mechanisms of synchronous commutations in switching converters and for numerical simulations.
