This paper presents a new multi-input bidirectional dc-dc converter which connects a fuel cell, storage and load by a combination of a dc-link and magnetic-coupling. A boost-dual-half-bridge and a bidirectional direct-connected switching cell are used. The topology is simple and only needs six power switches. The load and the sources are galvanically(More)
A zero-voltage-switched three-port bidirectional converter which is able to handle wide input voltage ranges such as fuel cells and supercapacitors is presented in this paper. The converter consists of three active bridges coupled by a three-winding transformer. A simplified duty cycle control method is introduced to extend the soft-switching range. The(More)
