Dual Active Bridge Control

This example shows how to control the output voltage of a dual active bridge DC-DC converter. Each switch is on for 50% of its switching period. A phase shift controller introduces a variable phase shift in the output bridge and controls the output voltage. The input voltage and the system load are held constant throughout the simulation. The total simulation time (t) is 0.25 s. At t = 0.15 s, the voltage reference changes.
