| Abstract |
The model based temperature control system examined in this paper increases the expected lifetime ofIGBT power modules by decreasing the magnitude of temperature swings occurring during operation.In order to achieve this goal additional power losses are produced during low load conditions. This iscarried out by presetting a reactive current. The three level neutral point diode clamped three phaseinverter drives a permanent magnet synchronous machine. The basic functionality is demonstrated ona simple test cycle. In order to illustrate the beneficial usage on a more complex load cycle a drivingcycle is exercised representing the electric vehicle as field of application. The improvement in regardto the expected lifetime and the generated additional power losses of the inverter and of the permanentsynchronous machine will be addressed and discussed. |
