N2 - In this paper, a novel multi-port bidirectional DC-DC converter with high voltage gain for fuel cell hybrid system is proposed. The proposed converter integrates a fuel cell power supply port, an energy storage unit port, and a load port, which can realize energy conversion between any two of them. This means that it has a high level of integration and can achieve the energy management of the hybrid system. Meanwhile, the switched-capacitor unit enables the converter to have the advantages of high voltage gain and low voltage stress. According to the relationship between power sources and load, five different operating modes can be defined. Then, the circuit structure and operating principle of the different modes are analyzed. Finally, simulation verifications are given to illustrate the effectiveness and feasibility of the proposed converter.
