Realization of a Smart: Electrolytic Capacitor Circuit: Electrolytic Capacitor Circuits that can Signal their Own Worn-Out State Have Arrived

THANKS TO THEIR LARGE capacity and low price, electrolytic capacitors are often used for filtering and energy storage applications. The major disadvantage of these components is their low reliability. Software and electronic modules have been developed to compute the lifetime of electrolytic capacitors online [1]-[3], but these monitoring systems haves three main drawbacks: □ They are rather expensive. □ They depend on the static converter structure. □ They cannot predict the fault of one capacitor if several capacitors are in parallel.
