| 摘 要： | 在太阳能光伏并网发电系统中，为了向电网提供最大的功率，要求并网逆变器输出电流与电网电压同频同相。为此，本文针对光伏并网逆变器提出了一种基于TMS320LF2407芯片的锁相控制方法，并给出了详细的设计思路，该方法简单实用，主要由软件编程实现，实验结果显示该方法具有很好的控制效果。

| Abstract: | In the solar photovohaic grid-connected system, the output current of grld-connected inverter is required to have the same frequency and phase as the voltage of electricity net in order to supply electricity net with max power. So in this paper a way of phase-locked control based on TMS320LF2407 is put forward in allu- sion to solar photovohaic grid-connected inverter and its detailed design way of thinking is given. The way is simple and practical, which can be realized by software. The results of experiment show that this method has good control effects. |
