Applications of power electronic devices in hybrid electric cars demand a higher allowed junction temperature of the power devices, if compact inverters close to the engine which use the combustion engine cooling circuit (with water temperatures up to T=115deg C) are required. Main challenge is the packaging technology. This paper reports on different power cycling tests, failure mechanisms and possible improvements.
