摘要：

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 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. And 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.
