| 摘 要： | 针对单相级联H桥型变换器,对其工作原理进行详细分析,提出一种适用于单相级联H桥型变换器的通用型多电平空间矢量脉宽调制(SVPWM)算法。该算法将单相多电平SVPWM简化为单相两电平SVPWM,不仅能够降低计算复杂度、具备优良的谐波特性,同时具备良好的扩展性。根据该算法,在单片现场可编程门阵列(FPGA)上实现单相七电平、九电平和十一电平SVPWM。基于DSP+FPGA与RT-LAB半实物实验平台实验结果验证了该算法的正确性与可行性。

| Abstract: | An algorithm of universal multilevel space vector pulse-width modulation (SVPWM) is proposed for single-phase cascaded H-bridge converter, after analyzing the operation principle of single-phase cascaded H-bridge converter. The proposed algorithm has the advantages of low computational complexity, low total harmonic distortion (THD) and strong scalability. It simplifies single-phase multilevel SVPWM to single-phase two-level SVPWM. This paper realizes single-phase seven-level, nine-level and eleven-level SVPWM on a single field programmable gate array (FPGA). Experimental results based on the hardware in the loop system with DSP+FPGA have verified the proposed algorithm. |
