Exploring Various MOS-Thyristor Associations for a New Power Integrated Function: the IGTH

Abstract

In this paper, various MOS-thyristor associations are investigated in order to develop a new integrated power switch : the IGTH, which combines a thyristor mode in the on-state and IGBT turn-on switching characteristics, allowing the turn-on current waveform control. This function offers the advantages of a thyristor on-state whilst reducing ElectroMagnetic Interference (EMI) due to hard switching modes. The physical behavior of the various MOS-thyristor associations are analized using 2D numerical simulations. An optimized device has been fabricated and experimental switching waveforms are presented.
