Abstract
In this paper, an averaged model predicting the dynamics of a zero-sequence current in parallel three-phase converters is developed. Based on the model, a new control variable associated with space-vector modulation is introduced. A strong zero-sequence current loop is designed to control and suppress the circulating current. Simulation and experimental results validate the developed model and the proposed control scheme
