Paper Title:
A 10 kV 4H-SiC Bipolar Turn Off Thyristor (BTO) with Positive Temperature Coefficient of VF, Current Saturation Capability and Fast Switching Speed
  Abstract

A novel power device configuration, the Bipolar Turn Off thyristor (BTO), was proposed and demonstrated in SiC. The BTO operates in anode switch configuration consisting of a 9 kV SiC p-type Gate Turn Off thyristor (GTO) and a 1600 V SiC n-type Bipolar Junction Transistor (BJT). Compared with SiC GTOs, several new features have been accomplished in the BTO: (1) A positive temperature coefficient of forward voltage drop, (2) Anode current saturation capability, and (3) A simple gate driver and fast switching speed.
