Abstract:In modern electrical traction drives, a variable dc-link voltage can be applied to increase efficiency in partial load. A dc-dc converter can supply a variable dc-link voltage and transfer energy between the battery and the dc-link. Hybrid cars combine the advantages of long driving ranges with the partial zero-emission operation. In series-hybrid drive trains, a switched reluctance machine can be used as a generator for the range extender unit. This paper presents at first the mechanism of energy transfer bet… 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.
