Abstract

This paper presents an algorithm for determining the State of Health (SoH) and the Remaining Useful Life (RUL) of wire-bonded power semi-conductor modules. It is hybrid in the sense that it combines the estimations of physically-inspired models and the on-line data acquisition. A key aspect is the analysis, modeling, estimation, correction and exploitation of the on-state voltage Von evolution. In this paper, the algorithm is demonstrated with a particle filter and with power cycling experimental tests performed until complete wire-bond failure.
