Aluminum electrolytic capacitors (AECs) are widely used in power electronic converters for filtering, buffering, bypass and storage purpose. Typical service life of AECs varies between 1,000 to 12,000 hours at rated condition. Operational life of these capacitor decreases due to various electrical and environmental parameters, thereby limiting the life of the converter system. Typically, capacitors...
Methods on reliability estimation and mechanism consistency test for accelerated degradation data are established in the paper. Firstly, according to the characteristics of the accelerated degradation data, the integrated degradation model is established with the Arrhenius relationship, which is used commonly in reliability engineering. Secondly, the confidence interval of percentile lifetime is given...
