DOI: 10.1109/jestpe.2019.2921012
Abstract: Megawatt-class power converters need insulated gate bipolar transistors (IGBTs) with kiloampere current ratings. Conventional IGBT power modules face difficulty to meet the reliability and over-current requirements due to bond wires, solder joint, and single-side cooling… read more here.
