Research and Application on New Generation of Traction IGBT Module Technology
The traction IGBT modules are the core power devices in the traction converters of modern railway locomotives for power convert and output. The new generation traction IGBT modules using the latest IGBT4, EC4 diode, VLD and DLC chips terminal edge technology which optimized design of chip areas and gate charges and had low on-state voltage, good electrical characteristics at high or low temperature and better performances of safe operation area. A new package with IHV-B housing had better internal chips layout and interconnect design to reduce stray inductance inside IGBT modules. The static losses of chips and the thermal resistance between the chip junction and module case could be reduced by increasing more chips active area. The improved power terminal structure had a good temperature distribution and better anti-vibration performance. The IGBT4 modules had passed a series of strict reliability tests with good environmental adaptability, power cycling capability and high reliability. Applying IGBT4 modules could improve the power density and integration of traction converter and make a miniaturized and lightweight solution for traction system with long lifetime.
