Fast control method in three-level inverter based on DSP and FPGA

在传统的三电平电压型逆变器空间矢量脉宽调制(SVPWM)控制算法基础上,结合"DSP+FP-GA",实现了一种快速的空间矢量调制算法,详细阐述了基于FPGA和DSP的硬件平台实现方法,实现了资源的最大化利用,提高了逆变器控制的快速性,为并网实验控制提供了更多资源。最后,通过仿真和实验结果对比验证了这一调制算法的可行性。

Based on the traditional space-vector pulse width modulation （SVPWM） algorithm for three-level inverter, a fast SVPWM algorithm was realized by using a ＂ DSP ＋ FPGA＂ combination. With the control method, the new method was carried out based on FPGA and DSP. The maximum utilization of the resources was realized, the rapiditay of the inverter control was im- proved, the more resources were provided for the grid connected experiment. Finally, simulation and experimental results were compared. It shows high degree of eoncordance.
