Gents,
I am working on a gate driver for a 3 phase inverter to drive an AC motor, everything seems to be working fine when the motor is stationary but as soon as i start the motor i have phase3 peak lopping (peak shaving).
the gate driver output is +-15V, +-30A, 4Watts maximum, and i am using it to turn three 1700Volt, 800Amp IGBTs.my problem could be the gate resistor (i am using 1.2 Ohm). does anyone have an idea about this problem?
could you please to explain how the peak looping happens?
any further information on how to calculate the gate resistor? what is the suitable value for my application?
My best regards
