4.4.5 Gate drive resistors
•
RGH - gate high resistor in series with the GH pin at the output of the GD3100
gate high driver and RoadPak module gate that controls the turn-on current for SiC
MOSFET gate.
•
RGL - gate low resistor in series with the GL pin at the output of the GD3100 gate low
driver and RoadPak module gate that controls the turn-off current for SiC MOSFET
gate.
•
RAMC - series resistor between RoadPak module gate and AMC input pin of the
GD3100 driver for gate sensing and active Miller clamping.
