摘要：
The input current ripple of interleaved floating dual boost converter (IFDBC) for fuel cell vehicle is large, making it difficult to meet the requirements of fuel cells. To solve this problem, a current-fed IFDBC with dc inductor on dc output is proposed in this paper. Compared to existing IFDBCs, the proposed converter can not only suppress the input and output current ripple but also offer lower switch stress, and better efficiency. The modulation strategy and operation modes of the converter are described in detail. In addition, to control the output power of the converter and balance the power of the submodule, a double closed-loop control strategy with input current feedback and inductor current of each submodule feedback is analyzed. Simulation results are presented to verify the effectiveness of the proposed topology and control approach.
