Abstract

For three-phase interleaved boost converters (IBC), the master-slave current balancing control is often used to cooperate with the voltage regulation control, but the tuning of the current balancing controller would have effect on the voltage regulation loop. In this letter, the decoupled master-slave current balancing control is proposed, and its small-signal transfer functions show that the voltage regulation loop and the current balancing loop are decoupled. A 300 W prototype of IBC is implemented to demonstrate the proposed control method.
