WebThe Zener diode Z1 is selected to set the VCElevel at which the protection will operate. Consequently, in the normal mode of operation, 15V is applied to the input to turn the transistor fully on, which also causes the diode D to be forward biassed through resistor R1. WebThe series gate resistor affects only the turn-on speed of the IGBT, the turn-off speed is largely determined by the IGBT it-self. A parallel diode, with the anode towards the gate, across the gate resistor is also recommended. The diode is reverse biased at turn-on but holds the gate down at turn-off, and dur-ing the off state.
