    How much do you know about the inverter braking unit

    Braking unit, the full name of "inverter-specific energy consumption braking unit", or "inverter-specific energy feedback unit", is mainly used to control the occasions where the mechanical load is relatively heavy and the braking speed is required to be very fast. The regenerative electric energy generated by the motor is consumed by the braking resistor, or the regenerative electric energy is fed back to the power supply. The main functions, advantages and action process of the braking unit are briefly introduced below.

    MOS damage mystery

    The working state of MOS in the controller circuit: turn-on process (transition process from turn-off to turn-on), turn-on state, turn-off process (transition process from turn-on to turn-off), turn-off state, and the main loss of MOS also corresponds to this. Several states, switching losses (turn-on and conduction), conduction losses, turn-off losses, and avalanche energy losses. As long as these losses are controlled within the tolerance specification of the MOS, the MOSwill work normally, and if it exceeds the tolerance range, damage will occur.

    How to deal with the serious situation of small current heating of MOS tube

    When doing power supply design or driving circuits, it is inevitable to use MOS tubes. There are many types of MOS tubes and many functions. For the use of power supply or drive, of course, its switching function is used. Regardless of N-type or P-type MOS tube, its working principle is essentially the same.

    Do you know all these knowledge points about power diodes

    Power diode is the most basic unit of power electronic circuit, and its unidirectional conductivity can be used for rectification, clamping and freewheeling of the circuit. The diode in the peripheral circuit mainly plays the role of anti-reaction to prevent the damage caused by the current backflow. Next, the editor will lead you to understand several major knowledge points about power diodes.
