  • Abstract
    The aim of this paper is to present an experimental off-line technique that can be used to estimate the condition of aluminum electrolytic capacitors. The aging of aluminum electrolytic capacitors is expressed by the increase of their equivalent series resistance (ESR) and the reduction of their capacitance. Thus, the proposed technique is based in the estimation of both ESR and capacitance values. To validate the theoretical equations some experimental and simulated results will be presented.
