Sinusoidal Asymmetric PWM modulation based three phase inverter

Regular sampling at positive and negative peak of carrier

The model simulates asymmetric modulation which can be observed at second scope by zooming the waveform on time axis. In this modulation technique the reference signal is sampled at positive as well as at negative peak of the carrier and held constant between two sampled points. Three phase inverter was used to demonstrate the effect of asymmetric modulation on the output and Fourier analysis is presented using GUI block.
