ABSTRACT:
A drive circuit for applying a supply voltage to a sending coil provides resonant coupling of the sending coil with the target coil regardless of changes in the inductance of the sending coil, as long as the resonant frequency of the sending coil is greater than the resonant frequency of the target coil. A controller provides variable delay intervals in the application of the supply voltage, thereby compensating for changes in the sending coil's inductance with the passage of time and proximity effects. The controller examines the reflected voltage induced in the sending coil by changing currents in the target coil to examine the degree of resonant coupling between the two coils and correct any mistuning.
