the main parts of the circuit are marked with a circle, part names and functions are as follows: 1: varistors, and its function is when the external voltage is too high, rapid changes in pressure-sensitive resistor very small, the fuse in series with the varistor is blown, thereby protecting other circuits will not be burned. 2: Fuse, specifications for 2.5A/250V, when the current in the circuit is too large, the fuse will blow to protect the other components. 3: induction coil (also known as choke), the main function is to reduce electromagnetic interference. 4: bridge rectifier, specifications for D3SB, the role of the 220V AC into DC. 5: filter capacitor, specifications for 180uF/400V, the role is to filter the AC ripple in DC, make the circuit more reliable. 6: op amp IC (integrated circuit), protection circuit, an important component of the voltage regulator. 7: temperature probe, power adapter used to detect the internal temperature, when the temperature is higher than a set value (different brands of power adapter, which set the temperature threshold is slightly different), the protection circuit will cut off the appropriate adapter's voltage output, thereby protecting the adapter from damage. 8: high-power switch, switching power supply is one of the core components, switching power supply to "opening and closing" to work, switch credit. 9: switch transformers, switching power supply in one of the core components. 10: secondary rectifier, the function is the low-voltage alternating current into low voltage direct current. IBM power adapter in, the rectifiers are often the work of two parallel power to obtain a larger current output. 11: sub-filter capacitor ac adapter Acer laptop ac adapter Dell laptop ac adapter Hp laptop ac adapter IBM laptop ac adapter Toshiba laptop ac adapter
