Abstract:
A reverse-blocking integrated gate-commutated thyristor (RB-IGCT) incorporating a backside PN junction, referred to as PN-RBIGCT, is proposed and investigated using Sentaurus TCAD. The introduction of the PN junction establishes a reverse electric field in the anode region during turn-off, which accelerates carrier extraction and reduces switching losses. At a conduction current of 5 kA, a 40.4% reduction in turn-off energy loss (from 335.6 J to 200.0 J) is achieved, with only a moderate increase in the on-state voltage drop of the PN-RBIGCT from 1.44 V to 1.62 V.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
