Wireless power transfer system transducers having interchangeable source resonator and capture resonator
First Claim
1. A wireless power transfer system, comprising:
- a source resonator including a first insulative split carrier-winder assembly having two identical and interchangeable halves, each half defining an interior core retaining pocket and an outer coil retaining surface, a first core tile formed of a material having high magnetic permeability and contained in the interior core retaining pocket of each carrier-winder assembly, and a first wire coil wound around the outer coil retaining surface of each carrier-winder assembly;
a capture resonator including a second insulative split carrier-winder assembly having two identical halves, each half defining an interior core retaining pocket and an outer coil retaining surface, a second core tile formed of a material having high magnetic permeability and contained in the interior core retaining pocket of each carrier-winder assembly, and a second wire coil wound around the outer coil retaining surface of each carrier-winder assembly, wherein the source resonator and the capture resonator are structurally identical and interchangeable;
a first housing configured to contain the source resonator;
a planar first resonator holder formed of a non-conductive material and configured to secure the source resonator within the first housing;
a second housing configured to contain the capture resonator; and
a planar second resonator holder formed of a non-conductive material and configured to secure the capture resonator within the second housing, wherein the first resonator holder and the second resonator holder are structurally identical and interchangeable.

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.
