摘　　要：本文针对UPS逆变器无互连线并联系统,结合均流的基本原理提出了均流的一种方案,并通过理论分析和仿真结果与原有PQ法进行了比较。结果表明,该方案在线性负载均流性能良好的情况下,能较好地解决非线性负载的不均流问题。In this paper, with the basic principles of current sharing, a improved scheme is proposed based on wireless parallel operation. According to the theoretical analysis and experimental simulation, it is seemed that the scheme is better than that using the original PQ method in linear load circumstances, and is a good solution to the nonlinear load problem of current sharing.
