Compute three-phase AC voltage from inverter DC voltage
Motor Control Blockset / Electrical Systems / Inverters
The Average-Value Inverter block models an average-value and full-wave inverter. It computes the three-phase AC voltage output from inverter DC voltage by using the duty cycle information.
These equations describe how the block computes the three-phase AC voltage.
