A Gate Driving Design Guide for CoolSiC MOSFETs


#1

Parasitic turn-ON caused by the Miller capacitance is often considered a weak spot of today’s silicon carbide MOSFETs. In order to avoid that effect, gate-drive designs for hard-switching converters are typically implemented with negative turn-OFF gate voltages. However, is that really needed with CoolSiC™ MOSFETs?
