摘要
针对小功率三相并网逆变器主电路拓扑结构,介绍了逆变器主电路、IGBT驱动电路、信号检测与调理电路的设计,采用数字芯片DSP28335在传统SVPWM控制方法下,将重复控制引入电流控制环,并给出了实现控制算法的程序流程。仿真和试验结果表明,基于DSP的小功率三相并网逆变器的性能满足并网逆变的要求。
Aiming at the main circuit topology of low-power three phase grid-connected inverter, the inverter main circuits, IGBT driving circuits, signal detection and adjustment circuits design are presented. The digital chip DSP28335 is applied to the inverter circuit control. And then the repeated controller is introduced into current control loop based on the traditional SVPWM control method. Finally, the program flow is given to implement control algorithm. The experi- ment and simulation show that the system meets the inverter grid-connected design requirements.
