摘要：针对风电变流器功率密度大、工作环境恶劣、满负荷运行时间长、功率波动大等特点，本文提出了大功率风电变流器直流侧母排设计原则及其结构设计要点。主要内容包括:减小母排电感、减小功率器件受力、母排防护等。最后对实际设计案例进行了剖析，进一步验证本文的主要观点。
叙词：风电变流器 母排 杂散电感 叠层母排 Abstract：This paper presented the design principle and structure design main points of the busbar, which used in high power wind power converter that had characteristics of high power densities, bad working conditions, full load long operation, power large variation. The main contents include reducing busbar inductance, reducing stress of power components, busbar protection, etc. At last, This paper analyzed the practical design case, the result further validated the main points of this paper. Keyword：Wind power converter, Busbar, Stray inductance, Laminated busbar
