Abstract
This paper addresses the requirements of networkscontaining linear inductors, capacitors and ideal switches forsynthesis of zero-order input impedance. Sufficient conditionsfor achieving zero-order input impedance are stated in terms ofthe network topology and the switching sequence. Such networkshave direct practical relevance to power factor correction (PFC).Based on zero-order switching networks, a comprehensive studyis presented for many existing PFC circuits as well as new circuit...Keywords
