GD32F330C8T6_4232BGM Introduction

In simple terms, the motor is driven by the output current of the MOS tube such as NCE80H12. The larger the output current (in order to prevent overcurrent from burning the MOS tube, the controller has limited current protection), the motor torque is strong and the acceleration is powerful, so MOS Tubes play a very important role in electric vehicle controllers.

The power mos used on electric vehicles is a three-dimensional structure. Low-power mos is a planar structure. The mos tube we have seen is actually composed of thousands of small mos tubes in parallel. You may think that one or a few bad moss should easily appear in thousands of small mos. In fact, it is not that easy. , the current manufacturing process basically guarantees the high consistency of various parameters of these small units.

Figure four types of MOSFETs and their graphical symbols. Power MOSFETs are generally rarely used in P-channel. Since the mobility of holes is lower than that of electrons, the on-resistance of P-channel transistors is larger than that of N-channel transistors for the same channel size. . According to the two points of the conductive channel and the process of channel formation, MOS tubes can be divided into: P-channel enhancement MOS tubes, P-channel depletion MOS tubes, N-channel enhancement MOS tubes and N-channel depletion MOS tubes .

However, in terms of structure, there is a big difference between them. In order to better understand the mechanism of power MOSFET, we must first recall the mechanism of low-power FET. . Working principle of power MOS tube Power MOS tube is developed from low-power MOS tube. The following describes the principle of the MOS transistor with the structure of an N-channel enhancement type low-power MOSFET.
