Fault tolerant VSI for drives and its control
PhD student: R. Errabelli
Supervisor: P. Mutschler
State: finished by PhD Thesis in 2012
For interlinked production processes, as in modern industrial processing plants, a fault in a single drive can result in tremendous damages of materials and machines. Follow -up costs due to faults with drives in modern production plants can amount to huge sums. Therefore, fault -tolerance will be a highly interesting feature for modern drive solutions.
In the research project, fault tolerant inverters for drives are systematically designed and analyzed. The inverter has to tolerate arbitrary single faults in
- the power section,
- in the signal processing and
- in the sensors.
Different topologies and methods have to be compared and the most promising solution has to be realized in hard- and software in an experimental set -up. The ability to tolerate faults is to be proven by theory and by experiment.
