摘要：

This paper encompasses the study of the output impedance impact of parallel-connected UPS inverters. Two novel nonlinear control strategies are proposed. The first one is based on the single-wire current-sharing scheme, which is well known in parallel dc-to-dc converter systems. The second one is a wireless control technique derived from the droop method. The output impedance of the inverters is investigated in both cases. Results of two parallel-connected 1-kVA UPS inverters show the feasibility of the proposed approach. Finally, the two proposed controllers are compared between them and those with the existing solutions.
