Sinusoidal Symmetric PWM modulation based three phase inverter

The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric regular sampling at positive peaks of carrier and fourier analysis of three phase inverter with this modulation technique. Symmetric modulation can be observed on the scope used by zooming the waveforms to large scale on time axis.
