In aluminum electrolytic capacitors, electrolyte is injected inside the capacitor, and the sealing material is tightened with the aluminum case to maintain a seal. However, as the electrolyte evaporates through the molecules of the sealing material, the amount of electrolyte inside decreases over time. As a result, the capacitance of the capacitor decreases and the

An electrolytic capacitor has several failure modes and causes. Electrical, thermal, mechanical, and environmental stresses cause the degradation of this component. The main failure mechanism is the evaporation of the electrolyte, which is accelerated with temperature rise during the operation, mainly due to ripple currents.
Therefore, the major factors affecting the lifetime of electrolytic capacitors in the power applications will be the operating temperature, the ripple current and the operating voltage. Other factors have minor affect to the lifetime and can be ignored in the calculation. 1. Influence of temperature on the lifetime model
Therefore, it is critical, in a predictive maintenance, to monitor the conditions (temperature, ripple current and voltage) of electrolytic capacitors in order to estimate the ESR and the capacitance evolution of the electrolytic capacitor.
Because of their high capacitance and voltage ratings with their cost-effective and volumetric efficiency, electrolytic capacitors have been widely used in power-electronic systems. However, this type of capacitors are one of the weakest components in power- electronic converter , .
The values of the stresses are chosen depending on the upper limit specifications of the capacitor under test. Two capacitor manufacturers are chosen for our tests to study the effect of different manufacturing processes on the degradation models.
