Abstract:This brief presents a zero-voltage switching (ZVS) Cuk converter with double-ended rectifier to reduce switching losses on power semiconductors, decrease voltage stresses on rectifier diodes, and achieve power delivery to the output load in both the positive and negative half cycles of the secondary winding voltage. An auxiliary switch and a clamp capacitor are connected in parallel with the primary side of the transformer to absorb all the energy stored in the transformer leakage inductance. The resonant indu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
