Abstract :
This paper presents a detailed study of the performance of a high-power IGBT module for application in a series resonant DC-DC converter. A novel test circuit has been developed that permits flexibility in test conditions without the complexity of full circuit operation. Experimental measurements are supported by finite element mixed device and circuit simulations. It is shown that considerable reduction in switching power loss is possible by a suitable choice of switching sequence. The numerical simulation structure very closely replicates the measured characteristics. With this initial simulation structure, full structural optimization can be explored for improved performance in the target application
