摘　　要：以差分功率变换为研究对象,通过对其常用拓扑的讨论,选择光伏-直流母线(PV-BUS)式DPP变换器架构来实现差分功率变换器处理最小变换功率的跟踪控制方法,通过MTALAB/Simulink建立仿真模型,验证了系统输出效率的显著提升。In this paper, DPP is taken as the research object. Through the discussion of its common topology, the PV-bus DPP converter architecture is selected to realize the tracking control method for DPP converter to process the minimum conversion power.The simulation model is established by MTALAB/Simulink to verify the significant improvement of the system output efficiency.
