NCE1450_NCEP0178F Introduction

In addition to the above-mentioned NCE80H12 suitable for electric vehicle controllers, Nanshan Electronics also provides Fenghua resistance-capacitance sense, long-crystal MOS transistors, Epson active and passive crystal oscillators, etc.

MOS tubes like NCE80H12 convert the DC power in the battery into AC power when the electric vehicle is running normally, thereby driving the motor to run.

. For these two enhanced MOS tubes, NMOS is more commonly used. As for why not to use depletion-type MOS tubes, it is not recommended to get to the bottom of it.

The reason is that the on-resistance is small and it is easy to manufacture. Therefore, in the application of switching power supply and motor drive, NMOS is generally used.

When the applied forward voltage increases, the concentration of unbalanced minority carriers increases and the concentration gradient also increases, and when the applied voltage decreases, the change is opposite. Diffusion capacitance: When a forward voltage is applied, the non-equilibrium minority carrier concentration near the interface of the depletion layer is high, far from the non-equilibrium minority carrier concentration is low, and the concentration gradually decays from high to 0 until it reaches zero. The process of charge accumulation and release in this phenomenon is the same as that of capacitor charging and discharging, which is called diffusion capacitance.

Another technique is to intermittently improve the structure of the MOSFET and use a straight V-groove structure. FIG. 3 is a cross-sectional view of the structure of a V-channel MOSFET. In order to avoid the problems of too small current-carrying capacity and large on-resistance of MOSFET, two techniques are generally used in high-power MOSFETs. One is to connect millions of low-power MOSFET unit cells in parallel to improve the current-carrying capacity of MOSFET. .

. For example, electronic fuel injection system, anti-lock brake control, anti-skid control, traction control, electronically controlled suspension, electronically controlled automatic transmission, electronic power steering, etc. The electronic device that can be used independently in the environment has no direct relationship with the performance of the car itself.
