New self-controlled and self-protected IGBT based integrated switch

摘要

In this paper, we present the realization of a new self-controlled integrated power switch dedicated to self-switching mode power converters. To achieve this function, an original topology based on an IGBT is proposed. Its operating modes are analyzed using 2D physical simulation. To realize this new power switch, a technological process compatible with the IGBT process and with 3D capacitors realization is proposed.
