Abstract

A new on-line electrolytic capacitor condition monitoring approach based on sliding mode concepts and the recursive least squares (RLS) with constant forgetting factor algorithm is proposed in this paper. This scheme involves robust exact differentiation which outperforms the classical differentiator based on linear approximations, when the system is affected by noise. The condition monitoring approach proposed in this paper allows for on-line estimation of the ESR which is considered to be one of the best indicators of capacitor degradation. Computer simulation results, considering a DC-DC buck converter, provide evidence of the effectiveness of the capacitor condition monitoring scheme proposed in this paper.
