What components of the switching power adapter are composed

         Due to the rapid development of microelectronics, the requirements for power supply systems for electrical equipment are now more complete in performance, higher in efficiency, lighter in weight, smaller in size, high in power and intelligent. Listen to Senshu strong power adapter manufacturers Xiaobian to introduce to you which components of the switching power adapter is composed.

1. Secondary rectifier, the function is to change the low-voltage alternating current into low-voltage direct current;

2, the inductor coil (also known as choke), the main function is to reduce electromagnetic interference;

3, the power adapter fuse, when the current in the circuit is too large, the fuse will blow to protect other components;

4, the filter capacitor, the role is to filter the AC ripple in the DC power, making the circuit work more reliable;

5. PWMIC (Integrated Circuit), an important component of the drive switch and voltage regulation;

6, the rectifier bridge, the role is to change the 100-240V AC into DC;

7, switching transformer, conversion voltage is one of the core components in the switching power supply;

8. The secondary filter capacitor acts to filter out the ripple in the low voltage DC power;

9. Power adapter High-power switch tube is one of the core components in the switching power supply. The switching power supply can work “open and close”, and the switch tube is indispensable;

10, varistor, its function is that when the external voltage is too high, the varistor resistance quickly becomes very small, the fuse in series with the varistor is blown, thus protecting other circuits from being burned out.
