Three-Phase Voltage-Sourced Converter (SPWM)

This example shows how to model a three-phase voltage-sourced converter that uses Sinusoidal Pulse-Width Modulation (SPWM). This modulation scheme compares a reference sine wave with a higher-frequency repeating triangle wave in order to generate the pulses. The model can be used to support selection of suitable values for L, C and the pulse modulation scheme parameters.
