摘要: A novel multiport isolated bidirectional dc-dc converter for hybrid battery and supercapacitor applications is presented, which can achieve zero voltage switching all switches in the whole load range. The power flow between any two of ports free, circulating low well matching transformer voltages time regardless variations supercapacitor. Moreover, current ripples are greatly decreased by interleaved control, good topology operation principle introduced. Detailed analysis on soft-switching given. On basis theoretical analysis, method parameter designing provided. energy management strategy combining bus control storage devices proposed scheme presented. detailed design a prototype given 380-V dc-bus microgrid lab system. Effectiveness strategy, correctness soft-switching, methods verified simulation experimental results.
