摘要：
The equivalent impedance mismatch and dead time mismatch could result in circulating current among the parallel inverters. To suppress the circulating current, a current-sharing method based on virtual impedance is added to the traditional resistive droop control in this paper. The simulation and experimental results are provided to verify the correctness and feasibility of the suppression method.
