With the development of power electronic technology and innovation to make power supply products market development is very rapid, technology is also in constant innovation, the cost of reversal points increasingly move to low output power end, for the power adapter and switching power supply products has provided a broad space for development. Switching power supply and power adapter used in homes, used in various industrial manufacturing, it has brought great convenience to our lives, and they move into a wider range of applications, especially in the high and new technology in the field of application, promoted the high-tech products of miniaturization, light change. But you will be asked about what is the power adapter? It and we use the switching power supply and what are the differences? Today just under analysis for everybody about the difference between the power adapter and switching power supply. Switching power supply, switching power supply is 220 v voltage into a method of low voltage dc, power frequency transformer which is different from traditional. Use this switch technology transform voltage of power supply are called switching power supply, charger and power adapter is currently used in switching power supply technology. Currently, switching power supply with the characteristics of small, light weight and high efficiency are widely used almost all electronic devices, is the rapid development of electronic information industry indispensable to a way of power supply. In addition the development and application of switch power supply in the aspect of saving energy, saving resources and protecting the environment has important significance. Switch power supply of the application of power electronic devices mainly for diode, IGBT, Insulated gate bipolar transistor) 。 In the switch power input rectifier circuit and soft start circuit in the application of a small amount of GTR drive difficulties, low switching frequency, gradually replaced by MOSFET and IGBT. Power adapter, power adapter is a small portable electronic devices and electronic power supply power transformation equipment, generally composed of shell, power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output; According to the connection mode can be divided into the plug wall and desktop type. Used in telephone composite aircraft, game consoles, the language repeater, walkman, notebook computers, cellular phones and other devices. Power adapter is generally not only can be used for power supply, can also be an electrical charge, like notebook power adapter, it can give the computer charging, can give the computer power supply. Most of the laptop power adapter can automatically detect 100 ~ 240 v alternating current (ac) ( 50/60Hz) 。 Basically all the external power supply, laptop and host connected by a line, so that we can reduce the volume and weight of the host, only a handful of the electricity supply model built in the host. Have a nameplate on the power adapter, marked on the power, input and output voltage and current, etc. Actually from the above we can know that the power adapter and switching power supply and our lives are closely linked, so we should spread the power of the basic knowledge in their life. Looking forward to small make up next to tell you about more knowledge about the power adapter.
