Abstract

Synchronous commutations (SC) occur in switched LCR circuits whenever two or more switching devices change state simultaneously. SCs are the basic feature of switched converters and their analysis is a key point in circuit simulation. The method presented in this paper is aimed at providing a simple and general tool useful both for theoretical inspection and numerical analysis of commutations in switching converters, even in presence of controlled sources. The method is based on the compensation principle and on a reduced hybrid resistive model of the circuit valid across the commutations. An example of hard commutations analysis in a voltage regulated dc-dc converter is presented.
