Studies demonstrate that the power converter has one of the click here highest failure rates in a wind turbine, with a key failure driver being the power module junction temperature (T(j)).This paper details an experimental setup for simplified emulation of wind turbine conditions on a power converter with infra-red sensing of IGBT T(j).Results are compared to previous simulation work for a PMSG wind turbine, with the same trend of increasing mean T(j) with wind speed found, and the need to use an equivalent generator reactance in highlighted.

A commercial-scale prototype for more accurate wind turbine lovesense 3 converter emulation is also detailed.
