Abstract
A multi-cell inductive wireless power transfer system includes multiple transmitting elements. Each transmitting element includes one or more transmitting windings and one or more transmitting magnetic cores. The multi-cell inductive wireless power transfer system also includes multiple receiving elements. The transmitting elements are separated from the receiving elements by an air gap. Each receiving element includes one or more receiving windings and one or more receiving magnetic cores.
Claims26
A multi-cell inductive wireless power transfer system comprising:
- a plurality of transmitting elements, each transmitting element including at least one transmitting winding and at least one transmitting magnetic core;
- a plurality of receiving elements, each receiving element including at least one receiving winding and at least one receiving magnetic core,
- wherein the plurality of transmitting elements are separated from the receiving elements by an air gap.
A power converter system comprising:
- a multi-cell inductive wireless power transfer system including a plurality of transmitting elements and a plurality of receiving elements, wherein each transmitting element includes at least one transmitting winding and at least one transmitting magnetic core, and each receiving element includes at least one receiving winding and at least one receiving magnetic core;
- a transmitting power converting circuit configured to convert an input power signal into a transmitting power signal to drive the plurality of transmitting elements;
- and
- a receiving power converting circuit configured to convert a transferred power signal received at the plurality of receiving elements into an output power signal to drive an electrical load.
A power charging system comprising:
- a charging station including a plurality of transmitting elements, each transmitting element including at least one transmitting winding and at least one transmitting magnetic core;
- and
- a vehicle configured to move independently of the charging station, the vehicle including a plurality of receiving elements, each receiving element including at least one receiving winding and at least one receiving magnetic core.
A method of controlling a power charging system, the method comprising:
- generating a magnetic field via at least one transmitting element among a plurality of transmitting elements installed in a charging station, the magnetic field generated in response to energizing at least one transmitting winding arranged adjacent to at least one transmitting magnetic core included in the at least one transmitting element;
- and
- positioning a vehicle including at least one receiving element among a plurality of receiving elements in proximity of the magnetic field to energize at least one receiving winding arranged adjacent to at least one receiving magnetic core included in the at least one receiving element;
- generating an output power signal in response to energizing the least one receiving element via the magnetic field;
- and
- charging a battery of the vehicle based on the output power signal.
