Triple pulse tester — Efficient power loss characterization of power modules

In this paper the triple pulse testing method and circuit for power loss characterization of power modules is introduced. The proposed test platform is able to accurately characterize both the switching and conduction losses of power modules in a single automated process. A configuration of a half bridge is tested by making a sweep of the junction temperature, dc-link voltage, and current for a given gate drive and dc-bus setup. Test results are presented for a 1700 V 1400 A IGBT power module.
