Online Failure Prediction of the Aluminum Electrolytic Capacitor
نویسنده
چکیده
The aim of this research is to present a simple online condition monitoring system to predict failure of the aluminum electrolytic capacitors used in the output LC filter of the switched mode DC–DC buck converters. Equivalent Series Resistance (ESR) is the best indicator of the failure of the aluminium electrolytic capacitors. The main idea of the proposed method is to monitor the ESR value and predict the failure of the aluminum electrolytic capacitor under operation in switched mode DC–DC buck converter. The proposed method provides a easy and direct way of online failure prediction of the aluminum electrolytic capacitor using a portable device with minimal hardware requirements .

One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...
