| 摘 要： | 针对直接计算式多相空间矢量PWM(SVPWM)算法复杂、难于拓展的问题,提出了一种基于零序信号注入的载波型多相逆变器PWM控制方法,该方法通过在正弦参考波中叠加一定的零序分量来改善PWM波的特性,实现了与高性能SVPWM同样的控制性能.分析了该方法的基本原理,推导了零序分量的变化范围,并给出了几种具有不同输出特性的零序信号实现方法.理论分析和实验结果表明,这种基于载波调制的多相PWM控制方法具有实现简单、综合性能好、易于拓展的特点.

| Abstract: | To solve the problems of complex arithmetic and difficult expandability in the direct-computed multi-phase space vector pulse width modulation (SVPWM) control, a novel multi-phase carrier based PWM control method based on zero-sequence injection is proposed. The proposed method can improve the output voltage characteristic through injecting some zero-sequence signal to the standard sine signal, and high performance can be realized as the SVPWM. The theory of the new method is introduced, and range of the ze... |
