초록

In this paper we proposed transient model for NPT(Non Punch-Through) IGBT(Insulated Gate Bipolar Transistor) with gate resistances. As gate resistance increases, turn-off time increases. But If gate resistance is small, overshoot voltage increase. To analyze the effect of gate resistance, the transient model is made and the experiments are conducted. We used gate resistances of values; 8[$\Omega$], 140[$\Omega$], 810[$\Omega$] for simulations and experiments. We compared theoretical and experimental results and obtained good agreements.
