What is the laptop adapter
3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).
1, laptop adapter, that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry said that the traditional laptop power adapter for the single-band notebook charger.
4, the working principle: the use of unstable power supply switching power supply principle through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop computer power supply and charging; it is worth noting that: this conversion circuit, there must be protection circuit (Overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.), to prevent accidents, the protection of the laptop will not burn.
2, the basic composition: input line + charger main body + output line + connector such as Acharger single-band notebook charger composition, which constitute the basic elements of the notebook charger, as inside the internal parts is very complicated.
