| Abstract |
In this paper the power cycling stress of the power semiconductors in wind energy applications for twocommon generator concepts (DFIG and gearless synchronous machine) will be investigated. The aim isto show how the chosen generator concept influences the power cycling stress of the power semiconductors. For the investigation regarding power cycling stress and estimated lifetime a wind speed profile of one month measured at the FINO 1 station in the German North Sea was used. With this it is possible to consider the power cycling stress caused by the output frequency of the generator as well as the power cycling stress caused by the cycles due to wind speed variations. |
