This application note covers the parasitic turnon effect due to the Miller capacitor and how it is mitigated using an Active Miller Clamp One of the common problems faced when operating an IGBT is parasitic turnon due to the Miller capacitor This effect is noticeable in 0 to 15 V type gate drivers (single supply driver). The active gate control technique on the Si device has been verified to be an effective tool to relieve the challenges above, especially to reduce EMI noise by slowing down dv/dt with less penalty of switching loss.

Under normal operating conditions, the gate driver is designed to turn off the IGBT as rapidly as possible in order to minimize switching losses This is achieved by means of low driver impedance and small gate drive resistance. One To limit the peak voltage, the gate resistors can be adapted or the voltage can be limited via a socalled "active clamping" circuit When limiting with the gate resistors, it should be noted that in modern IGBTs the switchoff process can only be controlled to a limited extent via the gate resistor 4 ½ VDC T1 T4 D1 D2 DCD4 AC DC T3. Here the gate control signal that also controls the gate driver (not shown for clarity) connects to the positive input of a comparator When the gate drive signal is asserted, the opencollector output of the comparator allows RDESAT to charge the capacitor CDESAT There is an RC charging curve for CDESAT, which provides the DESAT blanking time.
