Abstract

In this paper, a 270 V solid state power controller (SSPC) with 100 A nominal current rating is proposed. In order to realize the size and weight constraints of the SSPC, several MOSFETs in parallel are used, which must be capable of handling fault conditions such as, short-circuit and lightning strikes. In Here simulation work has been carried out using the state of the art of electro-thermal models of COOLMOS switches. SABER has been used to model this novel implementation, and using this approach it is possible to optimize the MOSFET areas, and the overall SSPC size.
