The misalignment and displacement of the coupled coils in an inductive power transfer system reduce the power efficiency and limit the amount of power that can be transferred. Coil misalignment results in the primary coil driver to operate in an un-tuned state which causes non-optimum switching operation and results in an increase in switching loss...

... the inductively coupled circuit in Fig. 1. The circuit consists of primary coil represented by inductance L P and its ESR r P , a secondary coil represented by an inductance L S and its ESR r S . The ESR of the primary and the secondary coils includes the ohmic resistance, the skin effect and the proximity effect. A capacitor C S is connected in parallel with the secondary coil to allow for resonant operation. Resistance r C represents the ESR of the capacitor which includes its dielectric losses. The load represented by a resistance R L is connected in parallel with the secondary coil. Inductance M represents the mutual inductance between the primary and secondary coils and is equal ...

In this paper, a one-stage dc-ac inverter with high boosting capability has been proposed. The proposed inverter topology develops the basic split-source inverter with a voltage-lift cell constructed from three capacitors, two inductors, and four diodes to increase the boosting capability. A relatively high voltage dc-dc boosting factor is achieved...
