As the switches must be turned on and off simultaneously in the proposed multi-input step-up converter based on switched-capacitor network, it is difficult to realize the independent control of each input source.Therefore, some changes were made for the structure of the switched-capacitor network, and research was done with an interleaving control.Firstly, the principle of operation and the performance of the double-input converter based on interleaving control were analyzed.And then the topology of the converter with n-input ports was presented by topology deduction.At last, simulation and experimental research was done.The results have shown that the proposed converter has a high voltage gain and allows all switches not to be turned on and off simultaneously with different duty-cycles, which realizes the independent control of each input source, and has more advantages in the field of new energy.
