4.4.5 Gate drive resistors
•
RGH - gate high resistors in series with GH_1 (strong gate charge/turn-on pin) and
GH_2 (weak gate charge/turn-on pin) and HybridPACK Drive module gate. These gate
drive output pins control the turn on of the SiC MOSFET gate and are enabled when
PWM is logic HIGH and setting match GS_ENH.
•
RGL - gate low resistors in series with GL_1 (strong gate discharge/turn-off pin) and
GL_2 (weak gate discharge/turn-off pin) and HybridPACK Drive module gate. These
gate drive output pins control the turn off of the SiC MOSFET gate and are enabled
when PWM is logic LOW and setting match GS_ENL.
•
RAMC - series resistor between HybridPACK Drive module gate and AMC input pin of
the GD3162 driver for gate sensing and active Miller clamping.
