Abstract

The invention is applied to the field of circuits and discloses a load driving circuit and an electronic load. The load driving circuit is externally connected with a power supply and a power supply to be tested. The load driving circuit comprises a voltage adjusting circuit and a load control circuit, wherein the input end and the output end of the voltage adjusting circuit are respectively connected with the power supply and the input end of the load control circuit, and the load control circuit is connected with the power supply to be tested. The load control circuit can adjust the electric parameters output by the power supply to be tested according to voltage output by the voltage adjusting circuit, so that the electronic load can finish power supply performance test on the power supply to be tested in different electric parameter work.

Description

technical field [0001] The invention belongs to the field of circuits, and in particular relates to a load driving circuit and an electronic load. Background technique [0002] Since each electronic product needs to be powered by a power supply, in order to ensure that the performance of the power supply meets the power supply requirements of the electronic product; for each special electronic product, it is necessary to test the electrical parameters such as the voltage, current and power of the power supply; during the test, The usual practice is to use an electronic load; however, a professional electronic load is very expensive, and there are not many test functions that are actually used, and the multi-functional electronic load is very bulky. Contents of the invention [0003] The object of the present invention is to provide a load driving circuit, the electronic load including the load driving circuit adjusts the current of the power supply to be tested to adjust t...
