With the implementation of the national energy-saving and emission reduction policy, LED energy-saving lamps have been accepted by the majority of consumers, and their brightness and power-saving effect are acceptable. In this case, the use of power adaptation will be further increased. With a population of more than one billion, the lighting consumption is a huge number, and the consumption of power adapter is also very huge.
Power adapters exist in many household appliances. We know that the power adapter plays the most important role in the use of computer LCD. Many electronic equipment can not be used under normal mains voltage, so power adapter must be used. The normal operation of LCD is also inseparable from the power adapter.
Electronic products have filled our life. In our daily life, the use of mobile phones, tablets and laptops is gradually increasing. At this time, the use of power adapters is also increasing. It can be said that the market development of digital products has driven the development of the power adapter industry.
The huge user group is the foundation of the development of the industry. Today, with the rapid development of science and technology, the explosive growth of various electronic products will certainly drive the vigorous development of ancillary industries. As the basis for the operation and use of these electronic products, the function of power adapter is irreplaceable.
Green. Green energy saving is the development focus of customized power products in the future. The strict requirements for environmental protection in China will make a variety of intelligent switching power supply technologies widely used, and make the power supply structure develop from centralized to distributed.
Miniaturization. Small high frequency switching power supply and its technology have become the mainstream of modern power supply system. Miniaturization and weight reduction of power supply are particularly important for communication power products. Therefore, improving the power density and power conversion efficiency of switching power supply, making it miniaturized and lightweight, is the goal of people's continuous efforts. As one of the main technical means of power miniaturization, high frequency and soft switching technology has become one of the research hotspots in the international power electronics field in recent years.
digitization. Digital power supply combines the high efficiency of switching power supply with the intelligent control of digital chip, and uses appropriate algorithms to adjust the voltage and current. Compared with analog power supply, digital power supply can accurately correct the current detection error, and the voltage detection is more accurate; It can realize fast and flexible control design.
Integration. In order to improve the reliability of the system, it has become a trend for complete machine manufacturers to cooperate with component manufacturers to develop "user specific" power modules. That is to install almost all the hardware of a complete machine into a module in the form of chips, so that a large number of components are no longer connected by traditional leads, and the parasitic parameters are minimized, so as to minimize the electrical stress borne by power components and power devices, so as to improve the reliability of system equipment.
