Evaluation of Power Losses and Ruggedness of SiC MOSFETs for use in High-Power High-Frequency Induction Heating Generators
Haukelidsæter, Knut (Master thesis, 2018)As the Si IGBTs are confronting its physical limitations when it comes to high-frequency high-power applications, the SiC MOSFET sails up as a promising substitute due to its material properties. However, in the process ... -
Merits of SiC MOSFETs for high-frequency soft-switched converters,measurement verifications by both electrial and calorimetric methods
Tiwari, Subhadra; Langelid, John K.; Undeland, Tore Marvin; Midtgård, Ole-Morten (Journal article; Peer reviewed, 2019)This paper quantifies the soft switching loss of a 1.2 kV SiC MOSFET module via a calorimetric method in a 78 kW full-bridge resonant inverter switched at approximately 200 kHz. By switching the SiC MOSFET just before the ...
