In this work we will focus on the short circuit destruction of IGBTs after turn-off. Electro-thermal device simulations and experimental verifications have been carried out to study the failure mechanism and identify the improvement potential. Heat diffusion to the front and back side chip surfaces after the short circuit pulse causes temperature rises at the pn-junctions which in turn inject thermally...
Freewheeling diodes are one of the major components for modern IGBT modules and have to satisfy a number of demands. Especially in hard switching applications, such as inverters for industrial drives or UPS, a soft switching behavior of the diode is - besides low losses and high ruggedness - of major interest. A high softness reduces EMI problems and enables a faster turn-on of the IGBT. In this work,...
This paper presents Infineonpsilas latest 1200 V power semiconductor generation: IGBT4 and EmCon4 diode. The new technology comes as a family optimized for applications in three different power levels: low, medium, and high power. Each part is balanced accordingly in its dynamic and static losses, switching frequency, and softness. In this paper the new technology is introduced, the electrical and...
