The status of IGBTs and IGCTs rated over 8kV

In order to help improve performance, size and cost of high power electronic systems, the development trend of power semiconductor devices continues towards achieving even higher blocking capabilities. This trend is fuelled by a number of applications in the fields of traction systems, industrial applications and HVDC converters. Also, new emerging high voltage markets such as pulse power applications are looking more likely to exploit the benefits of the newly developed high voltage devices. In this paper, we continue to follow the development trend by demonstrating a new range of IGBT, IGCT and their associated freewheeling diodes with blocking capabilities exceeding 8000V
