It is generally composed of a housing, a power transformer and a rectifier circuit. It can be divided into AC output type and DC output type according to its output type; it can be divided into wall plugging according to the connection method And desktop.</p><p><br></p><p><strong>Application of power adapter</strong></p><p><br></p><p>Power adapters are widely used in consumer electronics products. Most of the output power provided is within 100 watts, and market demand is growing rapidly. Such as electric bicycle battery chargers, small-size LCD TVs, notebook computers, printers, DVD players and set-top boxes have applications. Most of the early power adapters used linear transformers. With consumer electronics products requiring high efficiency, wide input voltage range, and increased copper, iron, and labor costs, the original linear transformers in these power adapters have gradually Replaced by switching power supply.</p><p><br></p><p><strong>Development trend of</strong><a href="https://www.fuyuanpower.com/power-adapter" rel="noopener noreferrer" target="_blank"><strong> power adapter</strong></a></p><p><br></p><p>The power adapter first appeared in the mid-1980s. Toshiba Japan used switching power supply technology as the external power supply for notebooks. Its pioneering work opened a new page in the history of the development of power adapters and became the world’s first independent Notebook power adapter, because the power supply using switching power supply technology is external, 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.</p><p><br></p><p>At present, the high frequency of power adapters has become its development direction. High frequency makes miniaturization of switching power supplies and makes <a href="https://www.fuyuanpower.com/power-adapter" rel="noopener noreferrer" target="_blank">power adapters</a> enter a wider range of applications, especially in the field of high and new technology, which promotes the development of high-tech products. Small size and light weight. In addition, the development and application of power adapters are of great significance in saving energy, saving resources and protecting the environment.</p><p><br></p>
