Abstract
Thermal levels in an inductor of a boost converter may be managed by implementing peak current limits for the boost converter. For example, an inductor may be allowed to conduct above a certain peak current limit for a certain period of time before the current is reduced by a controller to a low current limit. The controller may hold the low current limit in place for a certain period of time, after which the current through the inductor is allowed to again exceed the low current limit. However, if the high current limit is again exceeded or sustained for a certain period of time, the low current limit may be again imposed by the controller.
