Abstract—This paper discusses experimental setups for health monitoring and prognostics of electrolytic capacitors under nominal operation and accelerated aging conditions. Electrolytic capacitors have higher failure rates than other components in electronic systems like power drives, power converters etc.
Experiments are designed for aging of the capacitors such that the degradation pattern induced by the aging can be monitored and analyzed. Experimental setups and data collection methods are presented to demonstrate this approach.
Capacitance increase and loss can be taken into account. Under steady voltage and temperature stresses, capacitance can be considered as a reliable aging indicator since in such conditions, metallized polymer film capacitors suffer from the gradual loss of their electrode surface.
V. Conclusion The present work shows the ESR and capacitance of the electrolytic capacitor as ageing indicators. It also shows how previous works intended to use these indicators to predict the lifetime. The disadvantages of the offline step in these works made it crucial to rethink a new 100% online method.
Under high temperature and voltage test conditions, capacitance degradation can be considered as a reliable aging parameter since under such stresses, MPF capacitors suffer from the gradual loss of their electrode surface due to self-healing events.
