  • Entropy characterisation of overstressed capacitors for lifetime prediction 

    Cuadras Tomàs, Àngel; Romero, Ramón; Ovejas Benedicto, Victòria Júlia (2016-12-30)
    Article
    Accés restringit per política de l'editorial
    We propose a method to monitor the ageing and damage of capacitors based on their irreversible entropy generation rate. We overstressed several electrolytic capacitors in the range of 33 µF–100 µF and monitored their entropy ...
