IGBT Turn OFF Time Calculator

IGBT Turn OFF Time is the time it takes for the IGBT to turn off after the gate voltage has been turned off. It is important to note that the turn-off time is not instantaneous, and it can take several microseconds for the IGBT to completely turn off. Turn OFF Time Gate Voltage is affected by a number of factors, including the gate voltage, the gate current, the gate resistance, and the gate-source capacitance. The turn-off time can be reduced by increasing the gate current or by reducing the gate resistance. However, it is important to note that increasing the gate current or reducing the gate resistance can increase the switching losses and is represented as T_off(igbt) = T_dl(igbt)+t_f1(igbt)+t_f2(igbt) or Turn OFF Time (IGBT) = Delay Time (IGBT)+Initial Fall Time (IGBT)+Final Fall Time (IGBT). Delay Time (IGBT) is the time required by the collector current to charge the base emitter capacitance of a transistor device, Initial Fall Time (IGBT) is the time it takes for the collector current to fall from 90% to 10% of its initial value after the gate voltage has been turned off & Final Fall Time (IGBT) is the time it takes for the collector current to fall from 10% to 1% of its initial value after the gate voltage has been turned off.
