18/11/2015· The integration of high power silicon carbide (SiC) Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) in today’s power systems drives the demand for deeper understanding of the device switching characteristics by way of device simulation. Appliions like motor drive require power MOSFETs to drive highly inductive loads which increase the switching power loss by extending the
maximize the benefits of SiC (silicon carbide) modules. Cree’s CAS100H12AM1 1.2kV, 100A 50mm half- bridge module and Cree’s CCS050M12CM2 1.2kV, 50A six-pack module are used as examples.
Silicon carbide transistors are more expensive than similar silicon parts, but faster, more rugged and can be lower loss. The result is smaller lighter chargers, power inverters and motor controllers – something that is tempting electric vehicle makers, particularly, some claim, as overall system cost savings are to be had.
3/8/2020· Silicon carbide (SiC) based VSCs are more sensitive to dead-time from increased reverse conduction losses and turn-off time variability with operating conditions and load characteristics. An online condition monitoring system for SiC devices has been developed using gate drive assist circuits and a …
