in TIDA-00195 the parallel Capacitor in GE (C142,C71,C55,C38,C153,C164) are used to reduce the amount of inducted voltage at the bottom IGBT.
the question that comes to my mind is that using parallel capacitor in GE does not effect on rising and falling time ?
let's assume that we are using IGBT with input capacitor of 10nf in GE,and in addition we have 10nf parallel capacitor in GE .
the amount of draw current become doubled. and the rising and falling time increase am I right ?
question 2: by these unfair effects what is the benefit of using parallel Capacitor?
please explain more to understand about the benefit of it.
thanks for attention .
