摘　　要：由于可再生能源的输出电压水平较低,在并网的过程中须要使用升压变换器来提高电压水平。文章提出了一种高增益升压变换器,该变换器不仅能实现高电压增益,而且还能扩展电路结构以满足更高的升压要求。首先理论分析了所提出变换器的工作原理和开关器件应力,给出了器件参数设计方法;然后对比研究了该变换器的升压能力,分析了非理想器件对电压增益的影响;最后通过仿真模型和实验样机相结合的方法,验证了理论分析的正确性和可行性。Since the output voltage level of a range of green renewable energy sources is low,it is necessary to use Boost converter to increase the voltage level in the process of grid connection.A high gain Boost converter is proposed which not only achieves high voltage gain but also extends the circuit structure to meet higher boost requirements.Firstly,the operating principle and switching device stress of the proposed converter are theoretically analyzed,and the design method of the device parameters is given;then the boosting capability of the converter is comparatively studied,and the influence of non-ideal devices on the voltage gain is analyzed;finally,the correctness and feasibility of the theoretical analysis are fully verified through the combination of simulation model building and experimental prototype.
