Three-Phase Three-Level PWM Generator

This example shows how to use the PWM Generator (Three-phase, Three-level) to control a Three-Level Converter. The upper and lower supply voltages are input to a Neutral point controller, which balances the DC-link capacitor voltages. Reference AC waveforms are used as inputs to the PWM Generator. There are two time scopes: one for the controller waveforms and one for the load voltages and currents. When the model is executed, a Spectrum Analyzer opens and displays frequency data for the A-Phase Load Current.
