Three-Phase Three-Level PWM Generator

Open Model

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 is one time scope for the controller waveforms.
