Allow control to turn VCC/VEE flyback supplies ON/OFF:
•
Connect PS_EN (J25) jumper to 1-2
•
Utilize EN_PS signal (J5.10) to enable or disable the power supplies

4.4.6 Gate drive resistors
•
RGH - gate high resistor in series with the GH pin at the output of the GD3100 high-
side driver and IGBT gate that controls the turn-on current for IGBT gate.
•
RGL - gate low resistor in series with the GL pin at the output of the GD3100 low-side
driver and IGBT gate that controls the turn-off current for IGBT gate.
•
RAMC - series resistor between IGBT gate and AMC input pin of the GD3100 high-
side/low-side driver for gate sensing and Active Miller clamping.
