3 SiC MOSFET Gate Driver Design Considerations

SiC MOSFETs are used in high power systems and are primarily implemented in applications using high switching frequencies (>50kHz). Several gate driver design considerations are required to verify proper and efficient SiC MOSFET operation. This section describes the most important considerations for SiC MOSFET gate drivers.
