HOW NOT TO DESTROY AN IGBT

摘要

IGBTs are used to switch power in many products such as variable . frequency drives (VFDs), servo drives, electric cars, buses and trucks, trains, medical equipment (x-ray and MR), air-conditioners and even some professional audio systems. These are all termed 'high power' applications, which may lead them to be considered more electrical than electronic and therefore less sensitive. However, there are still a number of different failure mechanisms which will result in the destruction of the IGBT unless great care is taken during system design and operation.
