| 摘 要： | 本文介绍二极管箱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，最后用matlab／simulink仿真验证给出实验结果，证明了方案的正确性。

| Abstract: | In this paper, space vector pulse width modulation＇s basal theory and implement method is addressed for three-level NPC inverter, An optimized SVPWM algorithm for three-level PWM rectifier is stress analyzed, which is well suited for DSP implementation, Just through some simple arithmetic operations, we can calculate the duration time of the basic vector, Using TMS340F2812 for controllability flat roof to realize the system of three-level inverter, Finally, the validity and correctness of proposed SVPWM method is confirmed by matlab/simulink experiment results. |
