Parallel Current Sharing Control Algorithm Of Four Phase Interleaved Boost Converter

Interleaved boost converters are widely used in hydrogen fuel cell vehicles due to their good performance. In this paper, a parallel current sharing control algorithm of four phase interleaved Boost converter was proposed based on fuzzy control algorithm. The simulation model of topology control system of four phase interleaved parallel Boost converter was established by using MATLAB simulation tool. The parallel current sharing algorithm and fuzzy control parallel current sharing algorithm were used to control the four phase interleaved parallel Boost converter, and the influence of these two different algorithms on the system was analyzed. By comparing the simulation results, it was found that the system response speed was accelerated, the overshoot was decreased, and the output current ripple and voltage are decreased, which proved the superiority of the proposed control algorithm.
