Abstract
After a short comparison of the basic characteristics of 20 A, 2 kV MOS controlled thyristors (MCT) and insulated gate bipolar transistors (IGBT), both device concepts are analysed in the same hard switching circuit environment using mixed mode 2D device and circuit simulation tools. The focus of this comparative study is put on the controllability of current and voltage transients mandatory for device protection in unsnubbered circuits. This goal is easily met with the IGBT coupling feedback into the gate; MCTs enter oscillatory modes under such conditions and may eventually be destroyed.
