Virtual Temperature Detection of Semiconductors in a Megawatt Field Converter

A converter monitoring unit (CMU) that monitors the power modules of the converter in a multimegawatt test wind turbine is presented in this paper. A method of calculating the virtual temperature (T_{v}) of the power semiconductors is laid out. Contrary to previous work, the method enables T_{v} cha...
