Although the MOSFET parasitic CDS (CRSS) is very low, the high VDS dV/dt during turnoff can result in coupling enough charge from the drain-to-gate capacitance to reach the threshold voltage if negative drive and a close- coupled driver layout is not in place. 3.1 MOSFET Switching Transient...
This paper shows a gate driver design for 1.7 kV SiC MOSFET module as well a Rogowski-coil based current sensor for effective short circuit protection. The design begins with the power architecture selection for better common-mode noise immunity as the driver is subjected to high dv/dt due to...
