实现三相逆变器的闭环控制，基于电感电流和电容电流。实现逆变器的双闭环控制，动态性能良好，通过坐标转化为DQ坐标轴使得追踪精度良好，这里只提供了主函数部分，包括坐标变换，PI计算，相关的外设初始化，需要自己配置。(Realizes closed-loop control of three-phase inverters based on inductor current and capacitor current. Inverter dual-loop control, dynamic performance is good, through the coordinates of the DQ axis to make the tracking accuracy is good, here only the main part of the function, including the coordinate transformation, PI calculations, related peripheral initialization, you need to configure.)
