摘要

Multi-level VSI is most promising in high power, high voltage application environment. As the number of level increasing, the SVPWM is more and more complexity. In this paper, a new SVPWM method for multi-level VSI is proposed. This method is based SVPWM method for two-level VSI. By using a linear transformation, the dwell time of vectors for twolevel VSI can be transformed for multi-level VSI. A novel classification of voltage vectors is proposed to determine switching pattern of PWM sequence. The method can be extended five or more level VSI easily.
