摘要
传统的三电平空间矢量调制会产生较高的共模电压,对变频调速设备产生共模干扰.通过改变扇区的划分方法提出了一种新的抑制共模电压空间矢量调制策略。通过仿真验证了算法的正确性,对研究抑制三电平变频调速系统的共模干扰有一定的参考阶值。
The traditional three-level space vector modulation would result in higher common mode voltage, interferes frequency conversion drive device. Proposes a new suppressing common mode voltage space modulation strategy by changing sector division method. And the new strategy is verified by simulation referential to the study of suppressing common mode voltage of three-level frequency drive system.
