Spwm theory

WebSPWM is a comparison between a reference modulation (sinusoidal) waveform and a carrier (triangular) waveform which resulted in PWM (gate) signals for switching devices. The width of each respective PWM signal is proportional to the amplitude of a sine wave. Fig. 1 shows a typical SPWM generation theory and its resultant PWM signal.

At present, the methods of producing SPWM can be divided into two categories: hardware and software methods.

WebFig.2 is an example of the SPWM with modulation index more than 1. However, due to the variation of the sine wave refer-ence values during a PWM period, the relation between refer-ence values and the carrier wave is not fixed. This results in existence of harmonics in the output voltage causing unde-sired low-frequency torque and speed pulsations.
