Abstract
This paper presents the new concept of a p-base clamp, which remarkably improves the safe operating area (SOA) without sacrificing the low on-state voltage drop, for a MOS thyristor connecting a MOSFET and a thyristor in series. We demonstrate the effectiveness of this concept by using the experimental results from a 4 kV insulated gate controlled thyristor (IGCT) with a p-base clamp implemented by a Zener diode. The results show a very low on-state voltage drop of 3.75 V and a large SOA
