Abstract :
Investigations of the transient chip temperature of IGBT and diode in power modules are presented in this paper. The calculation of chip temperature and power losses occurs on-line in a microcontroller. Advanced practical results achieved in a step down converter are shown at different load cycles and output frequencies with the same average load current. An analysis of results and errors is also shown
