Abstract

In this paper, a newly developed simplified space vector PWM (SVPWM) method for three-level inverter is presented. The space vector diagram of the three-level inverter is simplified into that of a two-level inverter. So the selection of switching sequence and the calculation of the dwelling time is done as conventional two-level SVPWM method. The control of DC link neutral-point potential is easy to implement. The proposed SVPWM method can be applied to the multi-level inverter. The validity of the new SVPWM method is verified by simulation and experiment with a three-level IGBT inverter.

一种新的简化空间矢量三电平逆变器PWM方法

本文提出了一种新的三电平逆变器空间矢量PWM (SVPWM)简化方法。将三电平逆变器的空间矢量图简化为二电平逆变器的空间矢量图。因此，切换顺序的选择和停留时间的计算采用传统的两级SVPWM方法。直流链路中性点电位的控制易于实现。所提出的SVPWM方法可以应用于多级逆变器。通过三电平IGBT逆变器的仿真和实验验证了该方法的有效性。
