While this e book goes into further detail you can jump into the most relevant topics for your design at the right. The structure of an igbt power mosfet is such that the gate forms a nonlinear capacitor.
A mosfet driver is a type of power amplifier that accepts a low power input from a controller ic and produces a high current drive input for the gate of a high power transistor such as an insulated gate bipolar transistor igbt or power mosfet. A gate driver is a power amplifier that accepts a low power input from a controller ic and produces a high current drive input for the gate of a high power transistor such as an igbt or power mosfet gate drivers can be provided either on chip or as a discrete module. In essence a gate driver consists of a level shifter in combination with an amplifier. Need for a gate driver.
