| 摘 要： | SVPWM调制方法运用于级联型逆变系统时,由于电压矢量数目过多而导致电压矢量选择困难和复杂计算.为解决这个问题,从三电平逆变器的SVPWM调制入手,将SVPWM调制方法和移相技术结合起来分析,并采用数字信号处理器DSP和现场可编程逻辑器件FPGA,实现了对级联多电平逆变系统基于移相式SVPWM的矢量控制,仿真和实验验证都证明了该方法的正确性、可行性和易扩展性.

| Abstract: | A cascaded multilevel inverter based on SVPWM has a large number of voltage vectors, which makes selection and calculation of its voltage space vectors very difficult and complicated. In this paper, by analyzing SVPWM modulation in a three-level inverter, a method combines SVPWM modulation and phase shifted method is presented, and in a cascaded multilevel laboratory inverter system based on a DSP （digital signal processor） and a FPGA （field programmable gate array） are verified. Simulations and experimental results indicate the control is effective and easy to expand. |
