双面冷却条件下压接式IGBT结壳热阻测量与分析

Junction-to-case thermal resistance Rthjc measurement under a double-side cooling condition of press-pack IGBTs (PP IGBTs) is a great challenge since the heat flow through the two heat paths is hard to be accurately extracted. In this article, an indirect method determining the proportion of heat dissipation on both sides only by temperature measurement is proposed to simultaneously measure two si...
