Abstract
Thermal levels in an inductor of a boost converter may be managed by controlling an average current through the inductor. For example, a switching frequency of the boost converter between charging and discharging the inductor may be increased or decreased. Increasing or decreasing the switching frequency results in a corresponding decrease or increase in the switching period for the boost converter. The controller may adjust the switching frequency to control the average current level while maintaining a peak-to-peak current level in the inductor by monitoring the inductance of the inductor and the peak current level in the inductor.
