Power supply performance detection device

Abstract

The invention discloses a power supply performance detection device, which comprises a ripple sampling unit, a detection control unit and a load, wherein the input end of the ripple sampling unit is used for being connected with a to-be-detected power supply, the output end of the ripple sampling unit is connected with the detection control unit, and the detection control unit collects ripple values of the to-be-detected power supply through the ripple sampling unit; the input end of the load is connected with the to-be-detected power supply, the output end of the load is grounded, and the to-be-detected power supply reaches a full-load state when the load is connected with the to-be-detected power supply; the detection control unit is connected with the load and calculates the voltage ofthe to-be-detected power supply by acquiring the levels at the two ends of the load; and the detection control unit obtains a performance detection result of the to-be-detected power supply based on the ripple value and the voltage. The power supply performance detection device does not need to be set up during detection, is high in portability and low in requirement for the use environment, can be suitable for performance detection of the to-be-detected power supply in different environments, and can basically meet the detection requirement for the switching power supply at the market end.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power supply performance detection device. Background technique [0002] Switching power supply is the core accessory of electronic equipment. Basically, all equipment that needs to be charged and powered must be powered by switching power supply, and the abnormal output of switching power supply will seriously affect the working performance and even the service life of the equipment. At present, tests on whether the switching power supply can work normally are mostly carried out in laboratories at the production end, specifically, testing is performed through an oscilloscope, an electronic load, and an AC power supply equipped in the laboratory. [0003] However, since most of the laboratories at the production end are only used for the power supply detection of the switching power supply in the design stage and some random detection of the switching power supply produced,...
