中文摘要

为实现高功率密度和高效率,双面冷却功率模块在电驱动逆变器中应用广泛。然而,器件与双基板间的刚性互连带来了热机械可靠性挑战。本文提出使用多孔烧结银中间层来优化双面冷却模块的结构,以提升其热机械可靠性。

English Abstract

Low-profile double-side cooled power modules are emerging in electric-drive inverters to achieve higher power density and efficiency. However, the rigid interconnection between the devices and two substrates raises the thermomechanical reliability issue of double-side cooled modules. In the prior work, we proposed the use of porous sintered-silver (Ag) interposers in the double-side cooled modules...
