Detection and Diagnosis Solutions for Fault-Tolerant VSI [PDF]
Journal of Power Electronics, 2014 This paper presents solutions for fault detection and diagnosis of two-level, three phase voltage-source inverter (VSI) topologies with IGBT devices. The proposed solutions combine redundant standby VSI structures and contactors (or relays) to improve the fault-tolerant capabilities of power electronics in applications with safety requirements.
