Vienna Rectifier Control

This example shows how to control a Vienna rectifier. The Vienna rectifier subsystem consists of three-phase legs. Each leg has one power switch and six power diodes. The Control subsystem implements a closed-loop control strategy for the Vienna rectifier using space-vector modulation. Total simulation time is 0.1 s. At time 0.1 s, the Vienna Rectifier is engaged. At times 0.4 s and 0.6 s, the load steps up on the DC side.
