Abstract
A secondary side wireless power transfer compensation circuit includes a secondary coil, a capacitor in series with the secondary coil, and an inductor in parallel with the secondary coil and capacitor. The inductor has an impedance matching a reflected impedance of a load electrically connected thereacross such that the secondary coil achieves resonance with a primary coil coupled therewith at a predetermined frequency that depends on the impedance.
