The Principle Of AC DC Power Adapter

     DC power Supply (DC) can provide a stable DC power supply for the load of electronic devices. DC power supply power supply is mostly AC power supply, when AC power supply voltage or load resistance change, voltage regulator DC output voltage will remain stable. With the development of electronic equipment to high-precision, high stability and high reliability, the power supply of the electronic equipment is demanded.AC DC Power Adapter
     AC Regulated power supply (AC) provides a stable AC power electronic device for the load. Also known as AC voltage regulator. The output is alternating current, a variety of electronic equipment requires a relatively stable AC power supply, especially when the computer technology applied to various fields, the use of the AC grid directly power supply without taking any measures can not meet the needs.AC DC Power Adapter
     The internal of the AC adapter is mainly through the power transformer to complete the conversion output. The internal DC adapter is composed of rectifier circuit. At present, the common AC power adapter on the router has a copper core (wire pack) inside. When working, the power dissipation will be lost in the form of no effort, and the input voltage range of the line-pack power supply is very narrow, and can not adapt to various use environments. And the common DC power supply is the adapter (such as mobile phone charger, also known as DC switching power supply) inside is through the Rectification IC chip plus filter circuit composition, loss will be much lower.AC DC Power Adapter
     The difference between a power adapter and a voltage regulator: the power supply Adapter (adapter) is a small portable electronic device and electrical power supply converter, generally consists of shell, power transformer and rectifier circuit, according to its output type can be divided into AC output type and DC output type. Straightforward can be understood as a voltage converter, such as converting a 110-220 volt AC voltage to a fixed DC voltage. Voltage Stabilizer is the device that makes the output voltage stable. Voltage regulator with constant voltage, control circuit, and servo motor components. When the input voltage or load changes, the control circuit sampling, comparison, amplification, and then drive the servo motor rotation, so that the position of the voltage regulator carbon brush, by automatically adjusting the coil turn ratio, so as to maintain output voltage stability.AC DC Power Adapter
    Common AC power Adapters (hereinafter referred to as AC power) are usually fitted with the AC symbol, and the internal AC adapter is mainly through the power transformer to complete the conversion output. DC Power Adapter (hereinafter referred to as DC Power) is DC. The internal DC adapter is composed of rectifier circuit. At present, the common AC power adapter on the router has a copper core (wire pack) inside.AC DC Power Adapter
