Abstract

The invention discloses a direct current feedback electronic load. The direct current feedback electronic load comprises a mains supply rectifying circuit, a power supply circuit, a control loop, a DC / DC booster circuit, a voltage-multiplying direct current feedback circuit, a mains supply synchronous drive DC / AC circuit and a tested power supply. The direct current feedback electronic load overcomes the defects of existing electronic load products and is a novel power electronic device which is used for delivery tests of various power supplies and chargers and can simulate the charging and resistance load characteristics of various mobile phones; the direct current feedback electronic load can achieve stepless regulation of a simulated resistance value and the regeneration and utilizationof electric energy and has the advantages of being capable of saving the energy, free of high-frequency interference, small in size, low in weight, capable of saving the installation space, excellentin test performance and the like.

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 ...
