The gate resistor is connected in series with the cell control board's turn on resistor during turn on, and connected in
series with the cell control board's turn off resistor during turn off. The effective RgON is the sum of the cell control
board RgON and the gate clamp board resistor. Likewise, the effective RgOFF is the sum of the cell control board
RgOFF and the gate clamp board resistor.
The gate emitter capacitor allows independent control of the IGBT's dIc/dt without significantly increasing switching
losses and using a smaller value gate resistor. Cge increases switching losses by nearly 25% but reduces repetitive
turn on current by about 20%, reduces peak repetitive FWD turn off current by about 53%, reduces IGBT turn off
overshoot voltage by about 30%, and reduces IGBT OOS overshoot voltage by about 53%.
