Power electronics interface configurations for hybrid energy storage in hybrid electric vehicles

This paper presents a study of different converter topologies used in the design of hybrid electric vehicle drive trains with emphasis on the power electronic interface for a battery/ultracapacitor hybrid energy storage pack. Each of the topologies proposed in literature has its own advantages and disadvantages, thus choosing an appropriate topology depends greatly on the specified application, design and operation requirements. Several aspects have to be considered to obtain a reliable comparison among different power converter topologies.
