The Power Converter is one of the most expensive electrical components in a modern wind turbine. It is also seen that the power converter has a high failure rate. In the heart of the converter are IGBT powermodules. IGBT failure and subsequent breakdown of converter often causes completely stop in the energy production, associated with high cost. Converters available on the market today have few or no available signals for failure detection.
The goal of the project is to develop methods, measuring principles and IGBT gate control principles to predict and reduce converter failures for modern off and onshore wind turbines. This will reduce loss of production and thereby reduce cost and increase energy security.
