Abstract

This study deals with new integrated systems for power electronics applications including wide-gap semiconductors. Integration of Silicon carbide (SiC) components provides for instance new perspectives with higher temperature operating points than conventional Silicon (Si) semiconductors. The present work intends to study an integrated buck converter composed of a Silicon IGBT (Insulated-Gate Bipolar Transistor) and a Silicon carbide diode. By means of infrared thermography, an analysis of the thermal disparities induced within such a hybrid assembly under various electrical loads is proposed, regarding especially the consequences of the electrical power transfer and the spatial distribution of the thermal field.
