A family of 3-level IGBT modules from 10A to 600A equipped with Trench Gate IGBT and their thermal performance under typical conditions for UPS and PV inverter operation

摘要

Today’s renaissance of 3-level topology is a result of a topology inherent advantage of switching lossrnversus DC-loss which can be used to optimize the overall efficiency and size of equipment requiringrndedicated output filters. Covering a wide range of inverter power a family of 3-level IGBT modules hasrnbeen developed to address inverter’s needs for compactness, efficiency, low internal inductance andrnhigh reliability. The internal layout, the power chips and the thermal profile in a sample module hasrnbeen monitored by thermography and baseplate temperature sensor under varying load and powerrnfactor.
