Development of high power press-pack IGBT and its applications

Press-pack IGBT has been developed in recent years as a superior high power IGBT device to conventional IGBT module in reliability and performance. This type of IGBT is replacing GTO or thyristor in such applications as traction, power transmission and industrial motor drive because of its excellent advantages such as high performance, high reliability, compactness due to the both-sided cooling, rupture free feature, and so forth. This paper reviews the performance and structure of 2.5 kV and 4.5 kV press-pack IGBT's and their major applications.
