摘　　要：对直驱并网变流器主电路的设计进行了研究,主要包括:网侧滤波器的设计及计算、机侧滤波器的设计及计算、共模电压的消除。基于网侧和机侧的控制理论,利用MATLAB对其控制方法进行了仿真,并通过对1.5 MW直驱风力发电机组并网变流器样机的试验,证明了该设计方法的可行性。The main circuit of the full-scale power converter was studied. The design of the power circuit was introduced as well as the design method of line-side LCL filter and the generator-side du/dt filter, the elimination of common mode voltage, the brake unit, the pre-charging circuit and the control system. Finally, the control strategies of line-side converter and generator-side converter are both discussed and simulated. The experiments of the full-scale power converter for 1.5 MW permanent magnet direct-driven wind turbine demonstrate the correctness of the research results.
