摘　　要：风电变流器设计中,IGBT的散热设计非常关键,介绍了一种适用于风电变流器工程应用的IGBI损耗的理论计算方法,并建立了准确的数学模型。针对风电变流器应用环境的差异性以及不同类型散热器的固有热阻属性,通过flotherm仿真软件搭建普通散热器与热管散热器的仿真模型,仿真对比了不同散热器散热能力的差异。最后,通过实验验证了该设计方法的合理性和实用性,为风电变流器IGBT散热器与散热系统设计提供了重要的参考依据。Thermal design of IGBT is very important during wind power converter design.This paper introduces a theoretical calculation method of IGBT power loss which is applicable in wind power converter engineering applications. Meantime,the corresponding mathematic model is established.Considering the divergence of application environments as well as the inherent thermal properties of different types of radiators, simulation models of ordinary radiator and heat pipe radiator are built in flotherm.And the heat dissipation capacity of these two types of radiators is analyzed though simulation.Finally,experimental results indicate the rationality and practicability of the design,which provide critical references of IGBT thermal design and heat dissipation system design.
