Faults Location of Cascaded Inverter Based on Artificial Intelligence

Abstract:

Cascaded H-bridges inverter has been gaining its ground in recent years because it can satisfy high voltage and power applications with medium volume semiconductors; however, it uses much more semiconductors than the traditional inverters which would increase the fault possibilities. Just because this case Cascaded H-bridges inverter is limited in many important industrial fields. In this paper, we, firstly, discussed the basic unit of Cascaded H-bridges inverter (namely, full-bridge inverter) and classify its inner faults, then we proposed a method to spot the faulty IGBT using neural network. We have also done lots of jobs on this fields which could be seen in the papers of our team.
