Mechanism of gate voltage spike under digital gate control at IGBT switching operations

This paper reports the mechanism of gate voltage spike in the turn-off operation by a digital gate control. In the previous work, it was clarified that the gate voltage spike Vg_spike was generated by parasitic inductance and a large gate current change due to the digital gate control. However, the...
