Electrolytic capacitor self-repairing method and device, electronic equipment and storage medium

Abstract

The invention discloses an electrolytic capacitor self-repairing method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring time information, wherein the time information comprises a target time interval of current power-on and last power-off of an electrolytic capacitor in the power supply; under the condition that the target time interval is larger than a first threshold value, the power source is controlled to enter a self-repairing mode, and the self-repairing mode is a mode that the power source repairs the electrolytic capacitor. According to the method, whether the electrolytic capacitor needs to be repaired or not is judged by obtaining the time interval between the current power-on time and the last power-off time of the product provided with the electrolytic capacitor, if yes, the result is reported to the power supply, and the power supply is controlled to enter the electrolytic capacitor self-repairing mode, so that automation of the electrolytic capacitor repairing process can be realized; the electrolytic capacitor self-repairing purpose is achieved, and the service life of the power supply is prolonged.

Description

technical field [0001] The present application relates to the field of energy, and in particular to a self-repairing method, device, electronic equipment and storage medium of an electrolytic capacitor. Background technique [0002] Capacitors are passive electronic components used to store electricity and energy, and are one of the commonly used electronic components. Electrolytic capacitor is a kind of capacitor, its anode is a metal foil, the dielectric is an oxide film close to the anode metal foil, and the cathode is composed of conductive materials, electrolytes and other materials. Electrolytic capacitors get their name from the fact that the electrolyte is the majority of their cathode. As a core component, electrolytic capacitors are widely used in the field of electronic power technology and play important roles in support, energy storage, and filtering. For example, electrolytic capacitors are widely used in power modules of car charging piles due to their small...

Problems solved by technology

[0003] However, electrolytic capacitors are vulnerable parts

When it is in a power-off state for a long time, after the aluminum electrolytic is stored for a long time, a chemical reaction will occur between the anodized film of the capacitor and the electrolyte, resulting in a decrease in the withstand voltage of the electrolytic capacitor and an increase in the leakage current.

When suddenly powered on and loaded for a period of time, it may cause overvoltage failure of the electrolytic capacitor, or excessive leakage current may cause overheating failure, and even cause equipment damage
