WebNormally 0 V applied to the gate is enough to turn off the IGBT. However, to prevent voltage changes (dVCE/dt) across the Miller capacitance (due to the turning on of the opposite IGBT in the half bridge) from turning the gate of the OFF IGBT back on, a large negative voltage (-8 V to -15 V) is often applied to the VEE of the gate driver IC. It ... WebJul 19, 2014 · You need to bring the IGBT gate positive by something like 15V relative to the emitter to fully turn it on, and to drive it to zero (or a few volts negative) to fully turn it off. That should be done fast if you want the transistor to turn on snappily. It should never exceed something like +/-20V relative to the source.
