Abstract

This paper proposes a new current control strategy that is based on the internal model principle for a current balancer in single-phase three-wire distribution systems. The proposed current control strategy includes a sinusoidal reference input model to achieve the zero steady-state error tracking. The appropriate control gains of this control strategy can be systematically determined by using a state-feedback controller design method via linear matrix inequalities. The basic principle of the proposed control strategy is discussed in detail, and then confirmed by digital computer simulation using the PSIM software. A prototype experimental model is constructed and tested. Experimental results demonstrate that zero steady-state error tracking is achieved by the proposed control strategy. Also, balanced source currents are obtained on the secondary side of a pole-mounted distribution transformer while the load conditions are unbalanced.
