摘　　要：为了实现高效电能变换以并网发电,针对并网发电系统中光伏、燃料电池等清洁能源输出电压低的问题,提出了一种低输入纹波双开关高增益变换器。该变换器在实现电压高增益的同时通过将两个电感器的一侧连接输入端,可以实现输入电流的连续性以及降低电感电流。介绍了该变换器的工作机理以及参数设计方法,对比分析了不同高增益变换器性能。通过Matlab/Simulink对上述理论分析进行了仿真验证。仿真结果表明,该变换器能够实现直流电压的高增益,保证输入电流的连续性,同时减小了电感电流值。In order to realize high-efficiency power conversion for grid-connected power generation,a low input ripple dual-switching high-gain converter was proposed to solve the problem of low output voltage of photovoltaic,fuel cell and other clean energy in the gird-connected power generation system.The converter achieved high voltage gain,continuity of input current and low inductance current by connecting one side of the two inductors to the input terminal.The working mechanism and parameter design method of the converter were described,and the comparative analysis of the performance of different high-gain converters was carried out.The above theoretical analysis was simulated and verified by Matlab/Simulink.The simulation results show that the converter can achieve high gain of DC voltage,ensure the continuity of input current and reduce the inductance current.
