WebSPWM technique for a three-phase inverter. In the SPWM technique, the switching frequency of an inverter is equal to that of a carrier wave. From Figs. 7.29 and 7.31, we can see that the switch is turned on/off once every period of the triangular carrier wave. Thus the SPWM technique has an advantage of having a constant switching frequency. WebSPWM for Multilevel Inverter is based on classic two level SPWM with triangular carrier and sinusoidal reference waveform. (a) (b) Fig 3 (a) Vertically shifted carriers (b) Horizontally shifted carriers Only difference between two level SPWM and multilevel SPWM is, numbers of carriers are used in multilevel SPWM.
