Abstract

SHEPWM, a method to eliminate the selected low order harmonics by optimizing switching time sequence, has been concerned greatly because of its advantages such as high waveform quality, high efficiency, full utilization of DC side voltage and small size of DC side filter. In this paper, amathematic model based on thehomotopy algorithm is proposed to calculate the optimal switching time. The method is applied to three-level voltage inverters toshow the operations in detail. And to get more accurate value of switching time, the model is optimized with combining with Newton's method.
