For 2SC0535T2G0-33, Is ACL (active-clamping) the same as Miller-Clamping
Posted by: zmcginty

I'm asking because I'm testing this gate driver with an Eupec/Infineon FZ1200R33KF2C (I know there's a gate-drive module specifically made for this IGBT, but it is too expensive for my application). My application is pulsed power, and I'm getting very fast spikes in the gate line at turn-off, and others have mentioned I may need a miller-clamp. So I wanted to know if the advanced active clamping was for clamping the gate signal to be sure these spikes didn't exceed a maximum and fry the IGBT's gate?

Dear
Normally, the gate negative voltage is the easiest way to achieve the same function as miller-clamp circuit.
The advance active clamping is not a function that you expected to keep gate voltage stable.
from your waveform, if the yellow one is the gate voltage, please consider measurement noise.
The gate will be destroyed immediately , if there is a real 100V applied.
