Currently, he is a Ph.D. student in Electric and Computer Engineering at the same institution. His scientific activities focus efficiency analysis, fault detection and fault tolerance in electronic power converters, namely DC-DC power converters. Antonio J. Marques Cardoso (S'89–A'95– SM'99) received the Dipl. Eng., Dr. Eng., and Habilitation degrees from the University of Coimbra, Coimbra, Portugal, in 1985, 1995, and 2008, respectively, all in electrical engineering. From 1985 to 2011, he was at the University of Coimbra, where he was the Director of the Electrical Machines Laboratory. Since 2011, he has been with the University of Beira Interior(UBI), Covilhã, Portugal, where he is Full Professor in the Department of Electromechanical Engineering and Director of the CISE—Electromechatronic Systems Research Centre (http://cise.ubi.pt). He was Vice-Rector of UBI from 2013 to 2014. He is the author of the book Fault Diagnosis in Three-Phase Induction Motors (Coimbra Editora, 1991), in Portuguese, and approximately 400 papers published in technical journals and conference proceedings. His current research interests include fault diagnosis and fault tolerance in electrical machines, power electronics, and drives. Prof. Marques Cardoso was the General Chair of the 10th IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics, and Drives, Guarda, Portugal, in 2015, and of the 20th International Congress and Exhibition on Condition Monitoring and Diagnostic Engineering Management, Faro, Portugal, in 2007. He is currently an Associate Editor of the IEEE Transactions on Industry Applications, IEEE Transactions on Industrial Electronics, IEEE Transactions on Power Electronics, IEEE Journal of Emerging and Selected Topics in Power Electronics, and of the Springer International Journal of Systems Assurance Engineering and Management.L4

Abstract: DC-DC converters are becoming more commonly used in power conversion solutions for energy management purposes, being employed in an ever-increasing range of DC-based applications, such as LED lighting, electric vehicles, energy storage solutions, and consumer electronics (laptops, smartphones, etc.). In this context, efficiency and reliability are critical. The research efforts made in improving reliability of DC-DC converters are still quite narrow and scattered. Moreover, DC-DC converters take the shape of an endless number of topologies, with different functionalities and operation principles, thus complicating the task of improving reliability of all forms of DC-DC converters. Consequently, compiling the information about the main failure modes, corresponding fault diagnostic algorithms and fault tolerance strategies developed so far, in a single document, becomes increasingly necessary. Accordingly, this paper presents an up-to-date review of the recent achievements attained regarding the improvement of availability and reliability of DC-DC converters.

Key words: DC-DC converters, fault diagnosis, fault tolerance, reliability
