Description
technical field [0001] The invention relates to the technical field of capacitance aging detection, in particular to a capacitance aging detection system and method. Background technique [0002] Capacitance is a device that holds charges and is widely used in electronic equipment. As the use time increases, the performance parameters of capacitors will change. When the deviation error of performance parameters exceeds the standard tolerance, the capacitor is defined as aging. After the aging of the capacitor, the performance parameters of the corresponding electronic equipment will be reduced, and in severe cases, there may even be failures or equipment burnout and damage. Therefore, real-time monitoring and detection of capacitors to identify aging capacitors in advance and take corresponding measures has become an urgent problem. The problem. Contents of the invention [0003] The invention provides a capacitor aging detection system and method, which solves the proble...
