In the second half of the 1990s, development and commercialization of IGBT power modules for high voltage ratings as 2500 V and 3300 V has started. Originally, these HV-IGBTs were designed as GTO replacement for high-power and high-reliability applications like for example railway traction inverters [1]. Additionally, the use in many other high-power applications has followed.
