System and method for multi-coil dual backbone dynamic inductive power transfer
First Claim
1. An apparatus for wirelessly transferring power to a receive coupler, the apparatus comprising:
- a first coupler connected to a second coupler;
a third coupler overlapping the first coupler and the second coupler; and
a controller configured to;
receive power from at least one power supply,provide a first current to the first coupler and the second coupler in a first charging mode, wherein a magnetic flux generated by the first current passing through a first portion of the first coupler is constructively additive with a magnetic flux generated by the first current passing through a second portion of the second coupler,provide the first current to the first coupler and the second coupler and provide a second current to the third coupler in a second charging mode, andreverse a polarity of the second current provided to the third coupler in the second charging mode based on a location of the receive coupler.

Abstract
An apparatus for wirelessly transferring power to a receive coupler is provided. The apparatus comprises a first coupler connected to a second coupler. The apparatus further comprises a third coupler overlapping the first and second couplers. The apparatus further comprises a controller configured to receive power from at least one power supply, provide a first current to the first coupler and the second coupler in a first charging mode, and provide the first current to the first coupler and the second coupler and provide a second current to the third coupler in a second charging mode. A magnetic flux generated by the first current passing through a first portion is constructively additive with a magnetic flux generated by the first current passing through a second portion.
