Abstract
A system and method for providing acceptable output power from a wide range of received power, comprising: outputting a received voltage as an output voltage if the received voltage does not exceed a threshold; and limiting the output voltage to the threshold if the received voltage exceeds the threshold. Limiting the output voltage may comprise dropping an excess voltage across a switching element, wherein the excess voltage is the received voltage minus the threshold.
