| Abstract |
At medium voltage level the three level NPC converter is commonly used. As generator side converterin wind energy applications the diodes are most stressed and limit operation. The BIGT combines thefunctionality of the IGBT and the free-wheeling diode in one chip. The larger usable chip area in bothIGBT and diode mode decreases the maximum junction temperature as well as the junction temperatureripple compared to a conventional IGBT/diode module at the same output power. This leads to reducedpower cycling stress and improved lifetime. A lower maximum junction temperature enables an increasein output power. The potential of the BIGT in the NPC converter for wind energy applications is investigatedand compared to the conventional IGBT/diode module for a real wind speed over time profilemeasured at FINO 1 station in the German North Sea. |
