Abstract:This paper studies the approach of derivation of three-level (TL) half-bridge (HB) topology from conventional full bridge DC/DC topology. The derived TL HB topology has same device count and performance as the corresponding full bridge topology, and it is more suitable for high voltage applications. The derivation approach for different control method, i.e. PWM control, frequency control and phase shift control, are presented. Some novel TL HB topologies are proposed based on the approach. The experimental res… 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.
