Abstract

The invention provides a reliability tester for aluminum electrolytic capacitors, and relates to the technical field of electrolytic capacitors. The reliability tester comprises a power-frequency alternating current source, a power-frequency rectifier and filter module, an inverter module, a high-frequency rectifier and filter module and a pulse conversion module which are connected in sequence. The pulse conversion module is connected with an electrolytic capacitor to be tested. The reliability tester further comprises a direct voltage and current detection module and a pulsed voltage and current detection module. The direct voltage and current detection module is connected to the high-frequency rectifier and filter module. The pulsed voltage and current detection module is connected to the electrolytic capacitor to be tested. The power-frequency alternating current source, the inverter module, the direct voltage and current detection module, the pulse conversion module and the pulsed voltage and current detection module are connected to a control board. The control board is connected with an operation panel. By superposing a direct voltage and a pulsed voltage during experiment to simulate the working condition of the electrolytic capacitor to be tested, the use reliability of the electrolytic capacitor to be tested is detected.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolytic capacitors, in particular to the field of testing electrolytic capacitors, in particular to a reliability tester for aluminum electrolytic capacitors. Background technique [0002] Aluminum electrolytic capacitor is a very commonly used electronic component. Aluminum electrolytic capacitors have a certain working life, and the time is long. In the process of capacitor research and development, a very important parameter is to determine the life of new varieties. In order to test new The life of the sample requires a set of special equipment to test, to provide power for the capacitor during the experiment, and to simulate the working process of the capacitor. There is no power supply to provide energy for capacitance experiments in the prior art. Based on this, the present invention provides a tester to solve the above problems. Contents of the invention [0003] Aiming at the de...
