摘　　要：针对并网型分散式风力发电系统的需求,设计了能够实现并网运行的变流器。该变流器应用ZVS-PWM技术和平均电流模式控制方法,并采用最大电流自动均流法实现多机并联均流。实验结果表明该设计能够明显减少风电功率变换过程中的损耗,并且输出电流稳定,不会形成大幅震荡,证明该设计的正确性。According to the needs of distributed grid-connected wind power generation systems, the converter which can operate under grid-connected condition was designed. The converter use ZVS-PWM technique and the average current mode control method, and the use of maximum current flow to achieve automatic multi-parallel current. The experimental results show that the converter can significantly reduce the cost of wind power conversion process, with stable output current and not forming a sharp shock, which prove the correctness of the design.
