In the era of advanced high technology, consumer electronic products and various smart domestic appliances are gradually emerging, and China power adapters will be more widely used in the future.
The power adapter is a small portable electronic device and a power supply conversion device for electronic appliances. It is generally composed of a casing, a transformer and a rectifier circuit.
According to its output type, it can be divided into AC output type and DC output type.
According to the connection method, it can be divided into wall plug-in type (positive plug-in type, side plug-in type) and desktop type. In addition, most of the output power provided are within 100W, and the market demand is growing rapidly.
Most of the early power adapters used linear power supplies. With the requirements of high efficiency and wide input voltage range of power adapters in consumer electronic products, as well as the increase of costs of copper, iron and labor, for such power adapters, most of the original linear transformers are gradually replaced by switching power supply and power adapter.
The power adapter first appeared in the mid-1980s. Toshiba of Japan took the lead in applying switching power supply technology to notebook computers. It opened a new chapter in the history of power adapters and became the world's first stand-alone power adapter for laptops. Because the power supply in the switching power supply technology is external, the users of notebook computer no longer need to consider the heat generated by the power conversion to accumulate in the notebook computer itself, and the power adapter is easy to carry, so it effectively improves the commercialization and popularization of notebook computers.
At present, the high frequency of the power adapter has become the direction of its development. The high frequency makes the switching power supply miniaturized. The power adapter has entered a wider range of applications, especially the application of high-tech fields, which has promoted the miniaturization and lightness of high-tech products. In addition, the development and application of power adapters are of great significance in saving energy, saving resources and protecting the environment.
