In the era of advanced high technology

In the era of advanced high technology, consumer electronics and various smart life appliances are gradually emerging, and power adapters will be more widely used in the future.

The power adapter is a small portable electronic equipment and power supply conversion equipment for electronic appliances

The power adapter is a small portable electronic equipment and power supply conversion equipment for electronic appliances. It is generally composed of a housing, 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 type ( Positive insertion type, side insertion type) and desktop type. In addition, most of the output power provided is within 100 watts, and the market demand is growing rapidly. Most of the early power adapters used linear power supplies. As consumer electronics products require high efficiency and wide input voltage range for power adapters, as well as the increase in copper, iron, and labor costs, most of the original linear transformers in this type of power adapter are gradually being used. Replaced by switching power supply and power adapter.

The power adapter first appeared in the mid-1980s

The power adapter first appeared in the mid-1980s. Toshiba of Japan took the lead in applying switching power supply technology to notebook computers. Its pioneering work created a new page in the history of power adapter development and became the world's first independent notebook power supply. Adapter, because the power supply of the switching power supply technology is external, the notebook computer does not need to consider the heat generated by the power conversion to concentrate on the notebook itself, and the power adapter is easy to carry, and it effectively improves the commercialization and commercialization of the notebook computer. to make common.

At present, the high frequency of power adapter has become the direction of its development

At present, the high frequency of power adapter has become the direction of its development. High frequency has made the switching power supply miniaturized, and 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.
