Abstract

A power system comprises a converter including an inductor core defining a gap, and a separator spanning the gap and contacting the core. The power system also includes a controller programmed to, responsive to a decrease in current ripple amplitude output by the converter to less than a first threshold, decrease power supplied by the converter. The first threshold is indicative of an inductance change through the core due to a temperature driven decrease in size of the separator.
