Characterization of body diodes in the-state-of-the-art SiC FETs-Are they good enough as freewheeling diodes?
Tiwari, Subhadra; Abuishmais, Ibrahim Abed; Langelid, John Kåre; Lund, Richard; Midtgård, Ole-Morten; Undeland, Tore Marvin (Chapter, 2018)This paper investigates the switching phenomenon of body diodes in the state-of-the-art discrete SiC FETs. A comparative performance evaluation of the body diodes in planar and double-trench SiC MOS-FETs, and trench cascode ... -
Hard and soft switching losses of a SiC MOSFET module under realistic topology and loading conditions
Tiwari, Subhadra; Langelid, John Kåre; Midtgård, Ole-Morten; Undeland, Tore Marvin (Chapter, 2017)This paper investigates the switching performance of a 1.2 kV half-bridge SiC MOSFET module from Sanrex. Unlike in a standard SiC MOSFET module, where the MOSFET and the anti-parallel diode chips are fabricated separately, ... -
Soft switching loss measurements of a 1.2 kV SiC MOSFET module by both electrical and calorimetric methods for high frequency applications
Tiwari, Subhadra; Langelid, John Kåre; Midtgård, Ole-Morten; Undeland, Tore Marvin (Chapter, 2017)This paper investigates the soft switching performance of a 1.2 kV half-bridge SiC MOSFET module, FCA150XB120 from Sanrex. The selected module has both MOSFET and diode integrated on a single chip. A single pulse control ...
