My broadband router's power adapter is AC output, with this symbol. Who knows what the difference between AC adapter and AC output is? What are the pros and cons?
When the current in a circuit varies periodically with direction and intensity, it is called alternating current". Modern power plants produce electricity that is alternating current, household electricity and industrial power.I don't know, but I'm sure your route must be dc!
Specific advantages and disadvantages is not easy to say, this place to see specific applications!Because of its large transmission capacity, good stability and flexible control and adjustment, DC transmission has been welcomed by the power sector, and will have a further application prospect in china. In the development of HVDC transmission, attention should be paid to the research and application of hvdc. The development of modern high voltage direct current technology has opened up a broad prospect for the efficient transmission of power.
Alternating current: electric charge is the inherent property of matter. Normally, the number of positive and negative charges in an object is equal. Once the object loses or gets some electrons, it shows a negative or positive charge. A regular motion of an electric charge produces an electric current.Direct current: if in a circuit the charge flows in a constant direction, this is called "direct current"". In daily life, the current supplied by batteries is direct current. The battery has polarity. It is divided into positive and negative pole.
At present, the common AC power adapter on the router has a copper core (Xian Bao) inside.In operation, the power consumption will be dissipated in the form of no effort. The input voltage range of the wire package power supply is very narrow and can not be used in a variety of environments.The common DC power supply is adapter (such as mobile phone charger, also known as DC switching power supply), the internal is through the rectifier IC chip plus filter circuit, the loss will be much lower.
The common AC power adapter (hereinafter referred to as AC power) usually comes with the symbol "AC".DC power adapter (hereinafter referred to as DC power) is DC.The main part of the AC adapter is through the power transformer to complete the conversion output.The DC adapter is internally composed of a rectifier circuit.
