Model predictive PWM for AC motor drives

This study is for model predictive pulse-width modulation (PWM) for power electronics converters as AC motor drives. Compared with conventional PWM, model predictive PWM (MPP) employs the prediction model of PWM effect, and utilises the pulse arrangement freedoms to improve the performance of switching losses, current ripple and electromagnetic interference for the converter system. This study contains five parts including introduction, current ripple prediction method, variable switching frequency PWM, MPP for multi-level inverters and conclusions. The methods introduced in this study have been and can be applied in traction and industry motor drives.
