Abstract :
This article presents the fuel cell electric vehicle (FCEV) power supply system configuration, and proposes a topology of high power interleaved boost converter for fuel cell. With thorough analysis of the operating principle of the converter, eight equivalent sub-circuits are described. According to the waveforms of the inductor current, the operation modes of the converter are classified to six kinds, including CCM (continuous conducting mode) and DCM (discontinuous conducting mode), and the uniform state-space averaged model of the converter in CCM and DCM are developed. Based on the transfer function, the two-loop controllers are designed, and a prototype of 150 kW converter that is controlled by DSP-TI320F2407 is constructed. The volume and weight of the proposed converter are decreased 1/3 than conventional converter and the efficiency is over 97%. The experimental results show that the converter has excellent electrical characteristics, and it can be applied in the FCEV as well as the fuel cell distributed generation system
