Operating from an input voltage in the range 2.7 to 28V DC, the devices draw just 121μA of quiescent current (IQ). Switching times for the gate voltage (VGATE) are 0.58ms (ON) and 16.6μs (OFF). A high-efficiency power supply circuit can be realised by using one of the new driv...
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...
