%X 在基于开关电容网络的多输入升压变换器中，由于其开关管必须同时导通、同时关断，因此很难实现对各输入源的独立控制.基于此，对开关电容网络的结构进行改变，并采用交错控制策略进行研究.首先对基于交错控制的双输入升压变换器的工作原理及性能进行了分析，然后通过拓扑推演得到了n路输入的高升压变换器.最后，进行了仿真和实验研究，实验结果表明：该变换器不仅具有较大的电压增益，而且允许所有开关管不同时导通、不同时关断，并且占空比不完全一致，实现了各输入源的独立控制，在新能源利用方面具有一定的优势.</br>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.
