What happens when the IGBT drive waveform peaks?

Drive the peak of the waveform to see how high it is.

For example, the maximum driving voltage is 15V, and if it exceeds 15V, the IGBT may be damaged if it exceeds 20V, and the G withstand voltage of IGBT is about 20V.

It is suggested to connect a resistor in series in the driving circuit, about 22~43 ohms, 1206 package, which can alleviate this peak.

If the spikes are caused by other circuits, it is suggested to add TVS tube at G pole to filter out these spikes, and about16TVS tube can be added.

Finally, connecting a grounded 10K resistor in parallel with the G-pole also has a certain mitigation effect.

It is ok to add a small capacitor, but be careful, debugging is more troublesome. I have tested them, and they can achieve the same goal.

Of course, the power supply capacitance should be increased on the driver chip side. At least two 10uf capacitors, two 2.2uf capacitors and one 0. 1uf capacitor shall also be provided.

Basically, these can ensure transient changes and filter out power supply interference spikes.

By the way, your situation seems to be an overcurrent protection problem, not an overvoltage problem.
