Description

technical field

[0001] The invention belongs to the technical field of electronic loads, and in particular relates to a DC feedback electronic load. Background technique

[0002] With the rapid development of electronic technology, there are more and more portable electronic products with more and more powerful functions and greater power consumption. Such as mobile phones, digital cameras, DV, tablet PCs and electric vehicles, etc., in order to get a longer use time, the capacity of the rechargeable battery can only be increased, so that the charging time of electronic products is getting longer and longer, which is unacceptable . Therefore, major manufacturers have launched fast charging technologies one after another to solve the problem of too long charging time. Since the fast charging technologies and protocols of major manufacturers are different and incompatible with each other, it brings inconvenience, economic burden and waste of resources to users. It also puts ...
