Abstract

Power converter reliability is critical for permanent magnet synchronous generator (PMSG) wind turbines. Converter failures are commonly linked to the power module thermal loading. This paper models the expected converter thermal loading when the turbine is subjected to various synthetic wind speed conditions, including constant and square wave profiles. It was found that the model performed as expected compared to manufacturer's data and the diodes had greater thermal loading than the IGBTs. The preliminary results from synthetic square wave WSTS suggest that wind events with a period [gt ]5s are critical to the device thermal loading.
