| Abstract |
IGBT hybrid power modules used in railway applications are constituted of several dielectric
materials. When a high voltage is applied, this dielectric material stack may be a source of
partial discharges. We present a new method for determining partial discharges activity in
power modules. PD appears for voltages lower than the ones found according to the
normalized test. In this paper the method and possible sources of PD are investigated. |
