摘要
设计了一种基于三开关的改进型Sepic变换器,将其应用于光伏发电系统最大功率跟踪(MPPT)控制中。基于改进型Sepic变换器的光伏发电实验系统进行了实验研究,实验结果表明了采用该改进型的Sepic变换器在传输效率和故障隔离方面的优越性。
A novel improved three-switches Sepic converter was proposed based on analyzing the principle and composition of conventional Sepic converter,and was applied to photovoltaic maximum power point tracking（MPPT） system.A photovoltaic electricity generation prototype based on the improved three-switches Sepic converter was built in the laboratory.The experimental results prove that this improved three-switches Sepic converter can improve energy transmission efficiency and its application advantage at fault protection.
