A fully automatic aging system and method for a light source power supply

Abstract

This application discloses a fully automatic aging system and method for a light source power supply. The system includes a control circuit, an upper industrial computer and a plurality of identical aging units; the plurality of aging units are arranged in parallel; each aging unit includes a sampling resistor, a A power switch tube connected in series with the sampling resistor and an AD conversion circuit connected in parallel at both ends of the sampling resistor; the method includes that the upper industrial computer generates a matching program according to the model of the aged constant current power supply; the control circuit controls multiple aging units respectively according to the matching program; Collect aging files containing measurement results, and judge whether to terminate aging based on the aging files. The system and method provided by this application use the switch tube chopper circuit to replace the traditional fixed load, so that the impact strength can be improved under the premise of constant load strength, and the detection effect is better than that of the high temperature aging method, and this application adopts fully automatic operation , Reduce manpower demand, easy to manage, low equipment cost, excellent economy.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electrical component detection, and in particular to a fully automatic aging system and method for a light source power supply. Background technique [0002] During the production process of power modules, strict aging tests are usually required to ensure that the products will not have any failure problems after leaving the factory, and have high quality and service life. Aging test is also called roasting machine or burn-in machine, which is to test the performance of the product harshly, which means "try to burn it". Only products that have undergone the aging test are high-quality products, and ensure at least 24 hours of full-load aging. Only when the test is fully up to standard can it enter the market. [0003] At present, the conventional aging test method in the prior art is mainly the high-temperature loading aging method. This method is to place the product in an ag...
