Study of a Nine-Phase Fault Tolerant Permanent Magnet Starter-Alternator
نویسنده
چکیده
The paper presents a study on a nine-phase permanent magnet synchronous starter-alternator for automotive applications, analyzing different converter topologies, detailing the simulation programs and discussing the results in different operating conditions, from entire healthy machine to several faulted phases. The comparison between the two converter topologies controlling the multiphase machine highlights the increased fault tolerance, hence the reliability of such starter-alternator structures. Nevertheless, the article is within the area of interest of nowadays research in the field of automotive applications. Replacing two machines (the starter and the alternator) of a vehicle is the motivation for designing and studying starteralternator structures.

متن کاملPredictive Current Method for Single Open-phase Fault Detection in Permanent Magnet Synchronous Machine
Fault detection and post-fault operation are two functionalities of modern fault-tolerant system. In this paper, a new current predictive method for single open-phase fault (SOPF) detection in permanent magnet synchronous machine (PMSM) is presented. Major advantage of the proposed method is the capability of detecting open-phase fault in a few sampling intervals (few hundreds of μs). Also, an ...
