【摘要】 针对光伏发电系统中光伏电池板串并联带来的多峰值问题,基于自适应全局最大功率点追踪算法设计了最大功率追踪控制器。该设计以TMS320F28335 DSP芯片为基础,采用嵌入式μC/OS-II实时操作系统并加入了键盘、OLED显示器等人机交互界面。测试结果表明本控制器可以快速准确地实现全局最大功率追踪功能。更多还原

【Abstract】 For PV panels were series or parallel connected, the P-V characteristic curve of the system had multiple peak points. Adaptive global maximum power point tracking algorithm based on TMS320F28335 DSP was designed to solve this problem. It could be used to track the maximum power point effectively. Besides keyboard, OLED display and other interactive interface, embedded μC/OS-II real-time operating system were added aiming at improving the resource utilization of DSP and the stability of the whole system. Test results show that the system can work accurately and quickly when tracing the global maximum power point.更多还原
