Abstract:
Power conversion systems, which are using power semiconductors, are spreading in various fields. Especially in the traction field the requirements for higher current density, conversion efficiency and reliability are increasing. To fulfill those requirements, Fuji Electric has developed 1700V and 3300V “High Power next Core” (HPnC) IGBT modules based on the 7th generation “X Series” chip technology. Thus, the power dissipation has been reduced while the power density has been increased. A base plate with low linear expansion coefficient as well as ultrasonic bonding technology are used to improve the thermal power cycling capability and hence realize a higher reliability of the module.
