一种电源适配器额定寿命测试方法
摘要：
本发明公开了一种电源适配器额定寿命测试方法，所述方法包括：获取电源适配器，使所述电源适配器处于满载状态；对所述电源适配器进行高低温循环试验；所述高低温循环试验结束后，检测所述电源适配器是否失效；如果否，对所述电源适配器进行电磁兼容试验；所述电磁兼容试验结束后，检测所述电源适配器是否失效；如果否，对所述电源适配器进行平均无故障时间试验；在所述平均无故障时间试验进行第一设定时间后，计算所述电源适配器中所有电解电容的寿命；将所有电解电容中寿命最短的电解电容的寿命作为所述电源适配器的额定寿命。通过本发明，可以有效预估电源适配器的额定寿命。
摘要（英）：

The invention discloses a method for testing the rated life of a power adapter. The method comprises the following steps: obtaining a power adapter, and enabling the power adapter to be in a fully loaded state; performing a temperature cycling test on the power adapter; detecting whether the power adapter is invalid or not after the temperature cycling test is finished; if the power adapter is notinvalid, performing an electromagnetic compatibility test on the power adapter; detecting whether the power adapter is invalid or not after the electromagnetic compatibility test is finished; if thepower adapter is not invalid, performing an average fault-free time test on the power adapter; calculating the service life of all electrolytic capacitors in the power adapter after the average fault-free time test is performed for a first set time; and taking the service life of a electrolytic capacitor with the shortest life in all electrolytic capacitors as the rated life of the power adapter.According to the method for testing the rated life of a power adapter, the rated life of the power adapter can be effectively estimated.
