Shipurkar, U. (author), Lyrakis, E. (author), Ma, Ke (author), Polinder, H. (author), Ferreira, Jan Abraham (author)The power electronic converter, especially the power semiconductor, is a major contributor to the failure rates of the wind turbine drivetrain. As the temperature is a major driving factor behind the failure mechanisms of these power semiconductors the choice of topology and switching strategy can have a significant effect on the reliability...journal article 2018

Shipurkar, U. (author), Dong, J. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)Modularity is promising from a view to increasing turbine availability through fault tolerant operation as well as reduced downtimes, especially for offshore wind turbines. This paper focuses on a quantitative analysis of large scale (or extreme) modularity in power electronic converters of wind turbine generator systems. It uses mathematical...journal article 2018

Strous, T.D. (author), Shipurkar, U. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)In this paper, the brushless DFIM based wind turbine drive-train topology is compared to the DFIG based and PM generator based drive-train topologies, that are most commonly applied in modern wind turbines. The comparison will be based on a 3:2MW case study wind turbine. By using FE based multi-objective optimization, optimized generator designs...journal article 2016

Shipurkar, U. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)Availability is an important factor to be considered when designing wind turbine generator systems. The quest for increasing availability is based on the following five design approaches - design for component reliability, active control for reliability, design for fault tolerance, prognostics, and design for maintainability. This paper reviews...journal article 2016
