Do you know the working principle of the power adapter? How to repair it? Do you know it? I believe everyone is familiar with the power adapter. Laptops cannot do without the use of the power adapter, because the power adapter is used to charge and supply electronic devices such as laptops. , But many people do not know how the power adapter works or how to repair it. Here is a detailed introduction by our technical staff:
The working principle of the power adapter
The working principle of the power adapter is to use the principle of switching power supply to transform the unstable power supply into the constant voltage direct current required by the notebook computer through the conversion circuit, so as to power and charge the notebook computer. This conversion circuit must have a protection circuit.
The power adapter can use the principle of switching power supply to convert the unstable power supply into the constant voltage direct current required by the electrical appliance through the conversion circuit, so as to power and charge the electrical appliance. This conversion circuit must have a protection circuit (over-current protection circuit, over-voltage protection circuit, short-circuit protection circuit, etc.) to prevent accidents and protect electrical appliances from burning.
The switching power supplies and adapters are both switching power supplies, which are composed of high-frequency switching tubes and their control circuits. The adapter power supply is a regulated switching power supply. The switching power supply charger has a floating charge function. The voltage becomes larger as the current decreases, and in the end, there is only voltage but no current.
The working principle of the power adapter is like this. In fact, the power adapter is actually a high-precision and high-efficiency switch-type regulated power supply. Its function is to convert 220V AC mains power into low-voltage DC power and provide stable power for the normal operation of electronic equipment. .
