Fuzzy nano piezo hybrid for fault detection in automotive power PCB

Abstract

The paper addresses current issues on fault detection on high power automotive PCBs through the use of nano piezoelectric sensors. e-Mobility applications are gaining popularity each year and there has been significant improvement of the Power Electronics within these systems. At present there are two main approaches behind automotive traction inverters. The first is the use of power modules and second to use discrete parts (IGBTs or Power MOSFETs). Power modules have the advantage of a form factor which does not require a power PCB, having only power terminals and signal connectors yet are excessively expensive. The proposal within this paper relates to the second case when using IGBTs or Power MOSFETs and puts forth a proposal which evaluates how nano piezoelectric sensors may assist in the detection of faults or the proximity that a fault may occur at a certain time.
