Abstract :
This paper reports on the static and dynamic switching characteristics of an emitter switched thyristor (EST) for resonant power converter applications. Two-dimensional (2-D) mixed device and circuit simulations were used to study the carrier switching dynamics. It is shown that during turn-on, the EST has better performance than an IGBT with significantly enhanced drift region conductivity modulation. Thyristor-like on-state operation of EST leads to a slight degradation of the turn-off performance as compared to the IGBT
