Abstract :
This paper presents the experimental characterization of four different types of 4.5 kV, 91 mm asymmetric IGCTs under zero-voltage switching. On-state and turn-off tests at ratings up to 2.8 kV/3.3 kA with several resonant snubber capacitances and different junction temperatures have been performed to obtain experimental data. For converter loss modeling, e.g. dc-to-dc converters for offshore windfarms, the measured device losses have been used to derive a parameter-dependent fitting function.
