The effects of parasitic capacitance and inductance on the board can be considered a type of LC resonance. Please confirm the following conditions. 1) Increased external gate resistance connected to the gate drive circuit 2) Smaller gate drive circuit output capacitance 3) Reduced wiring parasitic inductance of the gate drive circuit When the resistance is small the overshoot/undershoot peak value will increase and prolong the ringing decay time. Also, a higher capacitance will slow down the switching speed. And we recommend that the inductance be as small as possible.
