WIRELESS POWER TRANSFER SYSTEM TRANSDUCERS HAVING INTERCHANGEABLE SOURCE RESONATOR AND CAPTURE RESONATOR
First Claim
1. A wireless power transfer system that transmits electrical power from an electrical power source to an electrical load using a source resonator and a capture resonator that are inductively coupled, characterized in that each resonator comprises:
- an insulative split carrier-winder assembly having two substantially identical halves, each half defining an interior core retaining pocket and an outer coil retaining surface;
a core tile formed of a material having high magnetic permeability and contained in the interior core retaining pocket of each carrier-winder assembly, anda wire coil wound around the outer coil retaining surface of each carrier-winder assembly, wherein two substantially identical resonators may be used interchangeably as the source resonator or the capture resonator.

Abstract
A wireless power transfer system that transmits electrical power from an electrical power supply to an electrical load using a source transducer and a capture transducer. The wireless power transfer system may be part of a wireless charging system for an electric vehicle. The source resonator coil in the source transducer and the capture resonator coil in the capture transducer are substantially identical and are interchangeable. The structures that hold the resonators in the transducers and the plates that provide a ground plane for the resonators in the source transducer and the capture transducer are also substantially identical and are interchangeable. Each resonator is formed of a carrier-winder, or bobbin, that has two substantially identical and interchangeable halves enclosing a magnetic core and is wound with a wire coil.
