The bilateral emitter switched thyristor (BEST)

Abstract

A new AC symmetric power device structure, called the bilateral emitter switched thyristor (BEST) is described. The use of concentric geometries for unit cells results in a compact and area efficient design. The symmetry of the device provides an additional MOS gate to facilitate turn-offs and to extend the controllable current range. The measured turn-off time is less than one microsecond.<>
