摘　　要：文中研究了一种基于单端反激变换器的DC模块电路，由它组成的光伏发电系统可以跟踪每块光伏电池板在不同光照、不同规格以及不同朝向等条件下的最大功率点。通过对光伏电池板直接串联时模拟阴影条件的性能测试，以及对以英飞凌公司生产的XE164F单片机为核心的光伏发电系统所做实验结果的分析，验证了系统设计的正确性。A DC module circuit composed of a flyback converter is discussed in this paper. A photovoltaic generation system based on this DC module can track the maximum power point of every photovoltaic panel under the situation of different illumination intensity, specifications and orientations. We test the performance of directly connected photovoltaic panels under simulated shading. On the basis of the test and the analysis of photovoltaic generation system based on Infineon XE164F96F66L MCU, we conclude our system is feasible.
