WebGenerally there are two types of dead time, the first one is control dead time and the second is effective dead time. The control dead time is the dead time, which will be … WebBut for low current switchings, the device voltage rise time decreases with the decrease in dead-time. The turning-on of the other IGBT of the same leg accelerates the rate of voltage transition. If dead-time is reduced to such an extent that the gate voltages of both the IGBTs are above the respective thresholds, shoot-through is observed. tiffany dowd
