Abstract
A wireless resonant power transmitter includes a first half-bridge and a second half-bridge adapted to be class D driven that are coupled to drive a series resonant circuit including a primary inductor (L) having a high side terminal and a low side terminal, and primary capacitor (C). A peak voltage sensor that includes a summing block is coupled across the high side terminal and the low side terminal of the primary L, and a peak-to-peak voltage detector is coupled to an output of the summing block to generate a DC voltage signal that is proportional to a peak-to-peak voltage across the primary C.
