Inductive power transfer assembly
First Claim
1. An inductive power transfer assembly comprising:
- a magnetic core having a base portion, a first limb, and a second limb, wherein the first limb and the second limb extend, in a direction, from a surface of the base portion;
a first power transfer coil and a second power transfer coil, wherein the first power transfer coil is wound about the first limb, and wherein the second power transfer coil is wound about the second limb; and
inverter circuitry connected to the first power transfer coil and the second power transfer coil, wherein the inverter circuitry, during operation, causes the first power transfer coil and the second power transfer coil to generate flux having opposing polarity.
