Abstract
In this paper, a new procedure to obtain the Reverse Biased Safe Operating Area (RBSOA) of a 4.5 kV self-aligned trench IGBT is presented. Using this procedure, the high voltage RBSOA boundary of a trench IGBT is directly obtained from its static blocking characteristics extended to very high current densities, thereby saving a large amount of computation time and effort required in obtaining the RBSOA through extensive dynamic simulations. In addition, observation of humps in the collector current waveforms during inductive load turn-off are also reported and analyzed.Keywords
