摘要
Abstract
The influence of active clamp and flyback circuit on output current waveform of inverter is analyzed.Aiming at the problem of power quality in current continuous mode,repetitive control mode is adopted to improve the waveform quality of output current and to reduce harmonic content.It is needed to track maximum power point of photovoltaic cells in photovoltaic power.In order to improve the effi-ciency of photovoltaic energy utilization,maximum power point tracking (MPPT)is required for photo-voltaic array.Combined with the constant voltage method and disturbance observation method,an im-prove maximum power point tracking algorithm is proposed,which improves the dynamic response speed.Combined with the sunshine conditions in the sunny days of Shanghai,the simulation test is car-ried out by using the photovoltaic simulator.The experimental results show that the repetitive control method can effectively improve the quality of output.The highest conversion efficiency is up to 94.2%, and the MPPT efficiency reaches 99.7%.The feasibility of the practical application of the product is verified by the experimental prototype.关键词
