Abstract
By testing the Case and the heat sink temperature of the same IGBT under the same conditions in the shells of different sizes of copper,thermal resistance of each conductive path is calculated to analyse the relationship between thermal resistance and the contact surface size. The size of the copper block power devices required for the safe temperature range is calculated according to this relationship,the feasibility of this conclusion is verified by FLOTHERM.a professional thermal simulation software. Finally,the temperature of power devices is measured, which is basically in line with the simulation. 关键词
