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.
