Energy-saving power adapter ageing testing device

Abstract

The invention discloses an energy-saving power adapter ageing testing device and belongs to the technical field of a power adapter. A group of power adapter ageing testing array of the device is connected to a commercial power grid or at least two groups of power adapter ageing testing arrays are connected to the commercial power grid in parallel; each group of power adapter ageing testing array is formed by serially connecting N power adapter ageing testing units and then serially connecting the N power adapter ageing testing units to an electronic load; each power adapter ageing testing unit comprises a to-be-tested power adapter, a power supply ageing special module and a relay. Compared with the current power adapter ageing testing equipment, the energy-saving power adapter ageing testing device has the advantages that required power supply equipment capacity of the device is reduced to 15 to 20 percent of that of the current power adapter ageing testing equipment, 85 to 90 percent of electric energy can be saved, the electric energy is not consumed on a resistor any more, the energy consumption is reduced, meanwhile, the production cost and the pollution to environment are reduced, and a power adapter which can be applied to test comprises alternating current-direct current electronic equipment for conversion, such as an electric vehicle charger, an LED (light-emitting diode) illuminating power supply and a computer power adapter.

Description

technical field [0001] The invention belongs to the technical field of power converter testing, in particular to a device for aging testing of power converters. Background technique [0002] A power converter is an electronic device that converts alternating current AC into direct current DC, and is widely used in electronic products such as chargers and adapters. [0003] Current AC / DC isolated power converters (hereinafter referred to as power converters), such as chargers, especially high-power battery car chargers, LED lighting power supplies and other electronic products, must be tested for 3-8 hours after production is completed and before entering the market. Aging test test, the test method is to apply the rated working conditions to the power converter plus the rated load. The load is generally an electronic load or a high-power resistance load. After a certain period of time under high temperature conditions, bad components are exposed to ensure product quality. I...

[0003] Current AC / DC isolated power converters (hereinafter referred to as power converters), such as chargers, especially high-power battery car chargers, LED lighting power supplies and other electronic products, must be tested for 3-8 hours after production is completed and before entering the market. Aging test test, the test method is to apply the rated working conditions to the power converter plus the rated load. The load is generally an electronic load or a high-power resistance load. After a certain period of time under high temperature conditions, bad components are exposed to ensure product quality. In the long-term power converter aging test process, a lot of precious energy will be consumed in vain, such as the production of aging 10Kw power converters, the continuous aging tunnel line is 100 stations, the power supply capacity must be greater than 1000Kw, 8 hours It will consume 8000 degrees of electricity, and the electricity cost will be tens of thousands of yuan, so that the electric energy of the power converter will be consumed in vain in the resistance during the aging test process, and it will increase the environmental pollution.
