摘要
利用有效矢量作用时间和均分零矢量的思想,提出了一种新型空间矢量脉宽调制方法,该方法简单实用,可方便地实现PWM正弦调制到方波的全调制区平滑运行。试验结果证实了该算法的有效性。
In this paper, a novel PWM algorithm is presented, which is based on the effective time and the average zero-vector idea, Using the proposed technique, which can be easily obtained and implemented by software, it is more flexible to control the inverter to transit from the linear control range to six-step mode. An experimental result shows the effectiveness of the proposed method.
