Two-Phase DC-DC Converter Current Control

This example shows how to control the current of a two-phase interleaved bidirectional DC-DC converter. The two-phase converter comprises two Bidirectional DC-DC Converter with ideal IGBTs. To adjust the duty cycle, the Control subsystem uses a PI-based control algorithm. To reduce the ripple at the output port of the converter, the two phases are switched with the same duty ratio but with a relative phase shift of 180 degrees. The Scopes subsystem contains scopes that allow you to see the simulation results.
