DC power adapters utilize modern power electronics technology to control the time ratio of switching transistors on and off to maintain a stable output voltage. The function of the DC power adapter is to convert the original ecological power supply (coarse power) with poor power quality, such as mains power or battery power, into a high-quality DC voltage (fine power) that meets the requirements of the equipment.
The heart of a DC power adapter is a DC/DC converter. Therefore, the classification of DC power adapters is dependent on the classification of DC/DC converters. That is to say, the classification of DC power adapters is basically the same as that of DC/DC converters, and the classification of DC/DC converters is basically the classification of DC power adapters.
