| 摘 要： | 针对光伏阵列模型之特点，提出了一种具有最大功率点跟踪（MPPT）的新型光伏阵列正弦波并网逆变器控制方案，该方案一改并网逆变器常规的双环（电压外环，电流内环）控制模式，而采而由MPPT控制器输出直接进行电流控制的新模式，使控制结构更加简单，动态性能更加优越，基于80C196MC控制的电流预估控制策略，实现了网侧电流正弦化，且为单位为功率因数。

| Abstract: | A new type of MPPT(Maximum Power Point Tracing)control method for sinusoidal courrent parallel feed inverter is presented in connection with the characteristic of photovoltaic array model.The proposed method is based on a new type of current control pattern with MPPT controller instead of on ordinary double closed loop(current loop,voltage loop)control pattern.By 80C196MC and current predicted tracking,the appropriate inverter takes its input current in an approximately sinusoidal waveform and its power factor to 1,which simplify the control system and improve dynamic characteristic. |
