| 摘 要： | 针对常规六相正弦脉宽调制(PWM)算法直流电压利用率低的问题,研究了一种基于双零序信号注入的六相载波脉宽调制算法。该算法通过在正弦调制波中注入一定双零序分量来提高六相逆变器的控制性能。分析了该算法双零序分量变化范围以及直流电压利用率的提升原理,给出了3种具有不同输出特性的双零序注入方法。通过对均值零序注入法进行仿真可以看出,该算法能增大直流电压利用率,改善系统运行特性,验证了该PWM算法的有效性和可行性。

| Abstract: | Aiming at the problem of low utilization of DC voltage in conventional sixphase SPWM algorithm, a sixphase carrier PWM algorithm based on double zerosequence signal injection was studied. The algorithm improved sixphase inverter control performance by injecting a certain double zerosequence component into a sine wave. The change range of the double zerosequence component of the algorithm and the principle of raising the DC voltage utilization ratio were analyzed. Three double zerosequence injection methods with different output characteristics were given. Through the simulation of the mean zerosequence injection method, it was seen that the algorithm could increase the utilization of DC voltage, and the system operating characteristics was improved, so that the effectiveness and feasibility of the PWM algorithm were verified. |
