The applications of AC to DC Power Adapter

In short, it is a voltage converter. Its main function is to convert the input AC into DC. The power supply required for the normal operation of our daily equipment is generally DC power supply, and the commercial power standard we use is AC 220V 50Hz, so we need a DC power supply voltage converter that can convert the AC 220V commercial power into the DC power supply required for the normal operation of the equipment. Take computers for example. Laptops need an external AC power supply (adapter), while desktops also need an AC power supply (adapter), but it is built-in inside the chassis. The charger of mobile phone, tablet, etc. is also a kind of AC power supply (adapter)
