| 摘 要： | 介绍二极管箝位式三电平电压空间矢量脉宽控制的基本原理和实现方法；重点分析一种易于DSP实现的三电平PWM整流器空间矢量脉宽调制优化算法，该算法只需进行简单的坐标变换，再经过普通的算术运算即可计算出各基本矢量的作用时间。以TMS340F2812为控制平台，DSP主要实现系统的初始化和脉冲输出功能，用matlab／simulink仿真验证给出的实验结果证明了方案的正确性。

| Abstract: | Space vector pulse width modulation's basic theory and implement method for three-level NPC inverter are presented.An optimized SVPWM algorithm of three-level PWM rectifier for DSP implementation is analyzed in detail. Through some simplearithmetic operations, we can calculate the duration time of the basic vectors. Using TMS340F2812 for control platform to realize theinitialization and pulse output of the system. Finally, the correctness of proposed SVPWM method is confirmed by matlab/simulinkexperiment re... |
