On reverse-conducting trench-IGBT modules

Infineon Technologies

High-voltage IGBT-modules usually consist of two types of IC, an IGBT for the transistor and a diode for the freewheeling functionality. A device that combines both functions in a single die is known as a reverse conducting IGBT (RC-IGBT). These modules exhibit a lower thermal resistance when compared to an IG
