For the power converters of Fuel Cell Electric Vehicles, there is a great need for less component stress, smaller component size and higher efficiency. The paper presents a typical configuration of FCEV power trains, and proposes a novel Buck-Boost cascaded topology for high power applications. It offers better performance compared with the single-switch buck-boost converters, such as buck-boost, CUK, Zeta, SEPIC circuit. Also, the operating principles and the parameters of the Buck-Boost cascaded converter are analyzed. The simulation results show that the converter has excellent electrical characteristics, and is suitable for FCEV applications.
