Hi all,
I have a problem when driving a mosfet via gate driver IC's. The input wave
has some noise on it and its causing the gate drive IC to turn on when its
not supposed to. This is happending on the rise and fall of the drive wave.
Such as on the rise its switching on and off very fast (probably in the mhz
range) before actually staying on with the input wave. . The only half
solution is to use very slow gate driver IC's which seem not to be able to
react fast enough to this oscilation and thus smoothing it out a bit. Though
its by far a cure.... anyone any ideas what I can do to filter out this
noise and stop the mosfets from turning on when they are not supposed to ?
thanks,
Chris
