Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a clamping power adapter. Background technique [0002] With the development of technology, the iterative update of electronic products has led to an increasing number of consumer electronics products, including laptops, tablets, smartphones, mobile devices, game consoles, printers, and stereo sound bars. These consumer electronic products all need to be equipped with a power adapter so that the power can reasonably drive the work of the consumer electronic products. As these consumer electronics products are gradually miniaturized and lightweight, it is necessary to reduce the size of the power adapter, and the demand for high efficiency and high operating frequency conversion effect of the power adapter is increased. However, the existing power adapters have some disadvantages. In the process of use, it is often encountered that the power conversion efficiency is low, t...
