33.如何减轻米勒电容所引起的寄生导通效应Mitigation Methods for Parasitic Turn-on effect due to Miller Capacitor White Paper Introduction Parasitic Turn-on Mitigation Solutions One of the common problems faced when switching There are three classical solutions to the above problem; an IGBT is parasitic turn-on due to Miller capacitor. This the first being to vary the gate resistor (Figure 2), second effect is noticeable in single supply gate driver (0 to to add a capacitor between gate and emitter (Figure +15V). Due to this gate-collector coupling, a high dV/ 3) and third to use negative gate drive (Figure 4). A dt transient created during IGBT turn-off can induce ……
