Power Adapter Which Components Are Formed
Power Adapter Which components are formed
Power adapter is composed of what components? Many related friends will ask, due to the rapid development of microelectronics, electricity equipment, power supply adapter requirements in the design of more perfect quality, more efficient, lighter weight, small size , High power and intelligence. Here to listen to the power adapter manufacturers Xiaobian to introduce the switch power adapter is what
Components made of
1. Secondary rectifier, the function is to low-voltage alternating current into low-voltage direct current.
2. Inductance coil (also known as choke), the main function is to reduce electromagnetic interference.
3. Power adapter fuse, when the circuit current is too large, the fuse will fuse to protect other components.
4. Filter capacitor, the role is to filter out the DC in the AC ripple, the circuit work more reliable.
5.PMMIC (integrated circuit), drive switch and voltage regulation of the important components.
6. Rectifier bridge, the role is to 100-240V AC current into DC.
7. Switching transformer, switching voltage is one of the core components of switching power supply.
8. Sub-filter capacitor, filter in addition to low-voltage direct current in the role of ripple.
9. Power adapter High-power switch, switching power supply is one of the core components, switching power supply can "open one" to work, switch tube contributed.
10. Varistor, its function is when the external voltage is too high, the varistor resistance quickly become very small, and the varistor in series fuse is blown, so as to protect other circuits are not burned.
12, the power adapter fuse, the standard is 2.5A / 250V, when the circuit current is too large, the fuse will fuse to maintain other components;
13, inductance coil (also known as choke), the main function is to reduce the electromagnetic interference;
14, rectifier bridge, the standard for the D3SB, the role is to 220V communication into DC;
15, the filter capacitor, the standard is 180μF / 400V, the role is to filter out the DC in the communication ripple, the circuit operation more solid;
