Abstract

The invention provides an energy-saving method for a product aging test. A product test parallel group, multiple product test series groups, corresponding independent product test series groups and independent product test parallel groups are included, wherein the front stage of the product test series group supplies power to the later stage; each independent product test series group compensates output current for the front stage; each independent product test parallel group shunts the current for the later stage; and current compensation and shunting are realized by controlling corresponding on-off switches through a constant current unit. The invention also provides a device for implementing the method. By using the method and the device, only a rated load is added at the output of the test product of the last stage, so that a large amount of energy consumption is saved; and by using the constant current unit for controlling the constant input current in test units, the stability of the product test is greatly improved.

Description

technical field

[0001] The invention belongs to the field of electronic circuits, and in particular relates to an energy-saving method and a corresponding device for product aging testing. Background technique

[0002] When the company leaves the factory and the user inspects the goods, the products such as switching power supplies or chargers it produces need to undergo aging tests. The aging time is divided into 4 hours, 8 hours, 24 hours and other methods. During the aging process, a large amount of electric energy is consumed in the form of heat generated by the load. In the existing product test mode, the output terminals of each test product are loaded with a load resistor for aging loading, that is, the test products are connected in parallel with each other. Due to the excessive load, the power consumption of this circuit form is too large. Facing its huge energy consumption problem. Contents of the invention
