摘　　要：提出了一种新颖的特别适用于太阳能与风能发电电力转换的单级单相升降压变换器,变换器4个功率开关管可以全部采用IGBT,其中二个也可以由可控硅替换,无需其他的任何额外开关。因此该变换器电路在实现高性能的同时降低了变换器电路成本费用。对提出的变换器进行了理论分析和建模,该电路设计理论经过光伏应用实验验证了其可行性和实用性。A new type of single-stage single-phase buck-boost converter is proposed,which is especially suitable for power conversion between solar energy and wind power.The four power switches of the converter can all use IGBT,and two of them can also be replaced by silicon controlled rectifier,without any additional switches.Therefore,the converter circuit can reduce the cost of converter circuit while realizing high performance.The theoretical analysis and modeling of the proposed converter are carried out.The circuit design theory has proved its feasibility and practicability through the photovoltaic application experiment.
