Abstract

This letter presents a scheme to balance the active power taken by an unbalanced load in a three-phase four-wire systems. It is shown that a power electronic converter, which operates under a control strategy based on the generalized instantaneous power theory, can redistribute active power between phases. The power source, therefore, only supplies balanced power, the negative and zero sequence components generated by the unbalanced load are prevented from flowing into the power system
