| 摘 要： | 为简化级联型多电平逆变器空间矢量PWM算法，提出了一种基于单元矢量移相叠加的空间矢量PWM控制方法（Phase Shifting Space Vector Modulation，PSSVM），采用数字信号处理器（Digital Signal Processor，DSP）和可编程逻辑器件（Complex Programmable Logic Device，CPLD）实现了对三单元级联型七电平逆变器的PSSVM控制，实验结果表明该控制方法可行，而且与传统多电平SVM方法相比，计算简单，易扩展。

| Abstract: | In this paper, a Phase Shifting Space Vector Modulation (PSSVM) approach is introduced firstly to simpli-fy SVM algorithm for cascaded multi-level inverters.Then Digital Signal Processor (DSP) and Complex Programmab1e Logic Device (CPLD) is used to realize PSSVM control of three-cell cascaded seven-level inverter. The experimental results indicate that the control method is feasible. Moreover, compared with the conventional SVM for cascaded multi-level inverters, the cal-cultation is simple and to expand easily. |
