Abstract

Disclosed is an FMIS method for a power module of an aerial parameter processing device. The FMIS method includes steps of determining critical components of a power module of an aerial parameter processing device; determining failure modes of the critical components; performing transient circuit simulation of the power module under a normal condition; and performing transient circuit simulation of the power module under a failure condition. By means of the FMIS method for the power module of the aerial parameter processing device, the failure modes of the power module of the aerial parameterprocessing device are determined based on a stress simulation method and failure mode injection technology, circuit output is obtained quantitatively in the failure modes, evidence is provided for design engineers to evaluate the influence and determine the harmfulness of the failure modes, and simultaneously for the design improvement of the power module.
