Abstract
A power control circuit for wirelessly powering a device is described. The circuit comprises a series of sub-circuits that condition and modify electrical power received from near-field resonant inductive coupling. In addition, the power control circuit consists of a reserve power source of at least one capacitor. A switching circuit consisting of an ideal diode OR-ing circuit is provided that receives and selects between the primary and secondary electrical power sources based on their measured voltages.
