The Development Trend and Market Prospect of Power Adapter

The power adapter is a Power Supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of a casing, a power 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 And desktop.

Application of power adapter

Power adapters are widely used in consumer electronic products. Most of the output power provided is within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small size LCD TVs, notebook computers, printers, DVD players and set-top boxes, etc. have applications. Most of the early power adapters used linear transformers. As consumer electronics products require high efficiency and wide input voltage range for power adapters, as well as copper, iron, and labor costs increase, most of the original linear transformers in this type of power adapter gradually Replaced by Switching Power Supply.

The development trend of power adapter

The power adapter first appeared in the mid-1980s. Toshiba of Japan took the lead in applying switching power supply technology to the external power supply of notebooks. Its pioneering work created a new page in the history of power adapter development and became the world`s first independent The notebook power adapter, because the power supply of the switching power supply technology is used externally, the notebook does not need to consider the heat generated by the power conversion to gather in the notebook itself, and the power adapter is easy to carry, which effectively improves the commercialization of the notebook computer And popularization.

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 allowed the power adapter to enter a wider range of applications, especially in the application of high-tech fields, which has promoted the development of high-tech products. Miniaturization and portability. In addition, the development and application of power adapters are of great significance in saving energy, saving resources and protecting the environment.
