Claim:
1. A circuit for delivering power to a load and from a wireless power supply, comprising: an inductor coil configured to couple to an electromagnetic field of another inductor coil of the wireless power supply; a rectifier configured to rectify power from the inductor coil of the circuit a switchable capacitor bank configured to store the rectified power in capacitors switchable at least between a series and a parallel configuration; a voltage detecting device including circuitry configured to measure voltages or detect predetermined voltages, across the capacitor bank; a switch controller including circuitry configured to control the capacitor bank switching in dependence on the measured or detected voltages; and a voltage regulator configured to supply the load with a constant voltage power supply derived from the voltages across the capacitor bank.
