Patent ID: 8742625

Claim:
A multiphase inductive power supply system comprising: a DC power source; a ground; a microprocessor; a plurality of tank circuits, wherein each tank circuit includes a primary inductive coupler and a capacitor; a plurality of oscillators, wherein each of said plurality of oscillators is electrically coupled to said microprocessor, wherein said microprocessor signals each of said plurality of oscillators to produce an oscillating signal in an out of phase relationship from each other of said plurality of oscillators, wherein said microprocessor signals each of said plurality of oscillators to vary a timing of said oscillating signal based on feedback from a remote device; a plurality of drivers, wherein each of said plurality of drivers is electrically coupled to at least one of said plurality of oscillators; a plurality of switching circuits, wherein each of said plurality of switching circuits is electrically coupled to at least one of said plurality of drivers and wherein each of said plurality of switching circuits selectively electrically couples said DC power source or said ground to one of said tank circuits to generate alternating current, wherein each alternating current is in said out of phase relationship; a multiphase inductive secondary circuit connected to said remote device with a plurality of secondary inductive couplers, wherein each of said plurality of secondary inductive couplers inductively couples to at least one of said primary inductive couplers in each of said plurality of tank circuits, wherein each of said plurality of secondary inductive couplers generates current in said out of phase relationship, wherein said remote device provides said feedback through said inductive coupling; a phase combination circuit electrically coupled to said plurality of secondary inductive couplers for combining said generated out of phase currents.
