Abstract :
This paper presents a method for online monitoring of power devices junction temperature in 3-phase power converters. The method considers power semiconductor devices and microcontroller chip aspects. Power loss calculation and thermal modelling is done using the 32-bit TriCore microcontroller. Practical results in a 3-phase inverter application are shown at different load conditions. With the proposed method, system optimisation and hence better chip utilisation can be achieved.
