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 LogicDevice,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。
In this paper, a Phase Shifting Space Vector Modulation （PSSVM） approach is introduced firstly to simplify SVM algorithm for cascaded multi-level inverters.Then Digital Signal Processor （DSP） and Complex Programmable 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 multilevel inverters, the cal-cultation is simple and to expand easily.
