Abstract

A generalized state space averaging (GSSA) technique for the analysis of a class of periodically switched networks has been proposed in the present paper. With GSSA, under the assumption that switching frequency is much higher than the highest natural frequencies of the networks, a periodically switched network with fast time-varying input sources can be handled. The GSSA is given as the main theorem in this paper, its application to the low-frequency analysis of quasi-resonant power converters (QRCs) has been illustrated via an example of a zero-voltage switching QRC boost converter
