Abstract: According to systems and methods of this disclosure, a controller may be configured to: operate in a first compatibility mode of operation, determine from an input signal of the lamp assembly during operation in the first compatibility mode whether the first compatibility mode of operation provides compatibility between the lamp assembly and a power infrastructure to which it is coupled, select the first compatibility mode of operation from a plurality of modes of operation as a compatibility mode responsive to determining that the first compatibility mode of operation provides compatibility between the lamp assembly and a power infrastructure to which it is coupled, and select a second compatibility mode of operation from the plurality of modes of operation as the compatibility mode responsive to determining that the first compatibility mode of operation does not provide compatibility between the lamp assembly and the power infrastructure to which it is coupled.

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.

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.
