Abstract

With growing electrification in transportation systems and widespread adoption of renewable energy systems, there is a growing need for the development of high-efficiency motor/generator drives that can perform well under a wide range of operating conditions with a high degree of robustness and fault tolerance. In this article, different components of the drive have been explored and some of the potential causes of failure have been identified. Furthermore, some configurations that can be used for increasing fault tolerance of the drive have been presented and some common approaches used for this purpose have been discussed.
