摘要
基于TMS320F2812芯片,阐述了一种单相光伏并网逆变系统的设计与实现方法.分析并设计了系统主电路,介绍了最大功率跟踪算法、电网跟踪控制以及电网电压锁相环的设计方法,并使用Matlab进行仿真,最后构建了实验室样机.实验结果表明并网电流波形良好,逆变器输出基本与电网电压同频同相,该方案可行.
The design of a single phase photovohaic grid-connected inverter system based on TMS320F2812 was presented. The constitute and designs of the software flow chart of MPPT, the inverter tracking control of power grid and the SPLL control of grid voltage were analyzed. Matlab based simula- tions for the inverter systems were carried out and a developed prototype was tested. Results showed the wave of grid connected current had the same frequency and phase as the utility voltage. The results con- finned the effectiveness of the inverter system.
