Gate drive requirements of IGBTs

The root of the answer is in the datasheet for the specific IGBT device you are using. It will state it's input capacitance and also it's output current curve Vs input gate voltage at a given collector voltage. From that you can determine what kind of drive capacity you must supply. As most IGBT devices are used in very high voltage and/or current circuits the use of special gate drivers is commonly called for.
