| 摘 要： | 在对太阳电池的等效电路及特性曲线分析的基础上．提出了最大功率点的跟踪（MPPT）方法，设计了一套基于DSP（TMS320F240）控制能实现最大功率跟踪的光伏并网逆变器，通过实际测试发现原有逆变器设计在跟踪最大功率点时存在运行不稳定的问题，经过分析提出了改进方案，实验证明改进后的逆变器运行更加稳定。

| Abstract: | With the analysis of equivalent circuit and character curve of solar array, the Maximum Power Point Tracking method was proposed and a DSP-controlled Grid-connected photovoltaic inverter with the function of Maximum Power Point Tracking was designed. However, the old inverter cannot run stably was found during the test. The new scheme was proposed by analyzing. The result of experiment showed that the improved inverter has better character. |
