The role of the power MOS in the electric vehicle controller is very important. Simply speaking, the output current of the MOS is used to drive the motor. The larger the current output (in order to prevent overcurrent from burning out the MOS, the controller has a current-limiting protection), the stronger the motor torque and the stronger the acceleration (the torque before the motor's magnetic saturation is proportional to the phase current).

IGBT is an insulated gate bipolar transistor. It is a composite fully controlled voltage-driven power semiconductor device composed of a bipolar transistor (BJT) and an insulated gate field effect transistor (MOSFET). It has both the high input impedance of MOSFET and GTR. two advantages of low turn-on voltage drop. In electronic circuits, IGBT is equivalent to a switch in electronic circuits, and is a semiconductor device driven by high power, high current and high withstand voltage.
