| 摘 要： | 描述了一种模数混合控制实现的光伏并网逆变器，介绍了在CPU速度受限制的条件下，采用模数混合电路实现运算控制并跟踪并网电流的方案。同时对光伏并网型逆变电源的结构及组成做了详细讨论。根据所提出的方案研制了一台三相并网逆变器，并网电流跟踪具有较高的分辨率，电流谐波小、噪声低，该逆变器已成功应用于20KWp的大型光伏并网示范电站。

| Abstract: | The structure and constitution of the inverter for grid connected photovoltaic system are presented in details. The mixed analogue-digital control algorithm is developed to track the current to the utility grid under limit of CPU speed. According to the scheme, a three phase grid connected inverter has been developed. The grid connected current has high differentiation and low harmonic components. The inverter has been put into use of 20KWp large-scale grid connected photovoltaic demonstration system, which has proved that the control algorithm works well. |
