IGBT modules robustness during turn-off commutation

The behaviour in terms of robustness during turn-off of power IGBT modules is presented. The experimental characterisation is aimed to identify the main limits during turn-off in power IGBT modules in typical hard switching applications. In this paper an experimental characterization of high power IGBT modules at output currents beyond RBSOA, at high junction temperatures and under different dr...

Advanced SOI Gate Driver IC with integrated VCE-Monitoring and negative Turn-off Gate Voltage for Medium Power IGBT Modules

A novel approach for medium power IPMs is presented combining 600V and 1200V IGBT/FWD-inverter modules based on spring contact technology with advanced silicon on insulator (SOI) gate driver ICs with fully integrated VCE-monitoring and negative turn-off gate voltage in a reliable cost effective package with excellent thermal conductivity. For the VCE-monitoring of short circuit events the HV-di...

Physical Modeling of Igbt Turn on Behavior

Although IGBT turn on losses can be comparable to turn off losses, IGBT turn on has not been as thoroughly studied in the literature. Under clamped inductive load condition at turn on there is strong interaction between the IGBT and the freewheeling diode undergoing reverse recovery. A physics-based IGBT model is used that has been proved accurate in the simulation of IGBT turn off. Both resist...

TCAD simulation of current filamentation in adjacent IGBT cells under turn-on and turn-off short circuit condition

Failure mechanism of trench IGBT under short-circuit after turn-off

Power semiconductor devices under short-circuit are submitted to high current and high voltage simultaneously that induce high electrical and thermal stresses. Several types of event leading to failure can appear under short circuit conditions in IGBT depending on the device structure, current load and voltage levels. One particular short circuit event appears once the device has turned off. Af...
