[0002] As the core components of electronic products, electrolytic capacitors play important roles in support, energy storage, and filtering. However, electrolytic capacitors are vulnerable parts, and their life is the bottleneck of electronic products.
If the life of the electrolytic capacitor expires, it will cause abnormal operation of electronic products, cause the equipment to stop working, and even lead to safety accidents

[0024] see figure 1 , figure 1 Shows the flow chart of the first embodiment of the electronic product life evaluation and testing method of the present invention, which includes:
[0025] S101. Acquire an AC ripple current measurement value of the electrolytic capacitor after the electrolytic capacitor in the electronic product is powered on for more than a first preset time.
[0026] The first preset time may be one minute or two minutes, but it is not limited thereto and can be preset according to actual conditions. For example, if the first preset time is one minute or two minutes, when the electrolytic capacitor is powered on for more than one minute, then start to acquire the AC ripple current measurement value of the electrolytic capacitor, that is to say, the AC ripple current The measured value is the ripple current value measured after the electrolytic capacitor has been powered on for at least one minute.
[0027] Specifically, the measured value of the AC ripple ...

[0057] S202, when the total working time of the electrolytic capacitor is within the preset time period, and after the power-on operation exceeds the second preset time, regularly update the standard value of the casing temperature of the electrolytic capacitor;
[0058] S203, when the total working time of the electrolytic capacitor exceeds the preset time period, regularly compare the measured value of the shell temperature of the electrolytic capacitor with the standard value of the shell temperature, generate a status percentage value, and send the status percentage value to the ou...

Abstract
The invention discloses an electronic product service life evaluation and test method comprising the steps that when an electrolytic capacitor is powered on and works for more than a first preset time, a state measurement value of the electrolytic capacitor is acquired, and the state measurement value comprises a shell temperature measurement value or an alternating current ripple current measurement value; when the total working time of the electrolytic capacitor is within the preset time period and the power-on working time exceeds the second preset time, the state standard value of the electrolytic capacitor is updated regularly, and the state standard value comprises a shell temperature standard value or an alternating current ripple current standard value; and when the total working time of the electrolytic capacitor exceeds a preset time period, the state measurement value of the electrolytic capacitor is compared with the state standard value at regular time to generate a statepercentage value, and the state percentage value is sent to the outside through the LED indicator lamp. The invention further discloses computer equipment and a computer readable storage medium. By adopting the method, the long-term state change (namely the state percentage value change) of the electrolytic capacitor can be effectively monitored, and the service life condition of an electronic product can be conveniently speculated.
Description
technical field [0001] The invention relates to power electronics technology, in particular to a method for life evaluation and testing of electronic products, computer equipment and a computer-readable storage medium. Background technique [0002] As the core components of electronic products, electrolytic capacitors play important roles in support, energy storage, and filtering. However, electrolytic capacitors are vulnerable parts, and their life is the bottleneck of electronic products. If the life of the electrolytic capacitor expires, it will cause abnormal operation of electronic products, cause the equipment to stop working, and even lead to safety accidents. Therefore, there are many domestic and international researches on the expiration of the life of electrolytic capacitors. [0003] After research, it is found that the main factor affecting the life of electrolytic capacitors is the temperature inside the electrolytic capacitor. Therefore, most of the life mode...
