摘　　要：在新能源联合发电系统中,现有的多输入直流变换器不能很好地满足其对供电方式、高增益、小纹波、低器件应力及高效率等工作性能的要求。基于此,给出了基于开关电容网络组的两种新型双输入升压变换器拓扑,即并联型双输入升压变换器和串联型双输入升压变换器,对其工作原理及工作性能进行了详细分析,并通过实验研究验证了这两种电路拓扑的正确性与可行性。In renewable hybrid power generation system, the existing multi-input DC-DC converters （MIC） cannot meet working performances requirements well, such as power supply modes, high voltage-gain, small ripples, low component voltage stresses, high efficiency and so on. Therefore, based on switched-capacitor network group, two novel double-input step-up converter topologies including the parallel-form and the serial-form are given. Operation principles and working performances of the two converters are analyzed in detail. In addition, experimental researches have been implemented to verify the correctness and the feasibility of the two circuit topologies.
