Its working is … Webperiod, its behaviour is similar to that of a MOSFET. The increase in drain voltage (dV/dt) is followed by a very fast fall of the switched current. Losses in this “dV/dt” period depend mainly on the speed of the voltage increase, which can be controlled by a gate drive resistor. The second “tail current” period is specific to the IGBT. how do you block someone on android
