Abstract：This paper proposes a fatigue damage of aluminum electrolytic capacitor estimate approach based on the theory of linear accumulated damage. The fatigue and aging mechanism of electrolytic capacitor is first analyzed, together with its influencing factors. Accumulated heat effect of ripple current is selected to be the dimension of capacitor’s fatigue damage and fatigue limit, and its damage degree to capacitor is calculated. With the summary of the damage degrees, overall fatigue damage to the capacitor can be directly estimated. This paper also presents the iterative computation approach of damage degree.
