Abstract

The design of a 55 kW 3X dc-dc converter is presented for hybrid electric vehicle (HEV) traction drives. It can interface the battery with the inverter dc bus with three output/input voltage ratios and have smooth transition in voltage ratio changes. By making use of the parasitic inductance, the size and weight of the converter are significantly reduced. Its magnetic-less feature and high efficiency provide the great potential for the very high temperature operation. The circuit parameter design and the circuit modeling are provided. Experimental results are given to verify the analysis and design concepts.
