Abstract
Wireless power transfer (WPT) systems having first and second primary windings and a secondary load winding are described. The WPT systems are configured such that the mutual inductance between the first and second primary windings is zero or substantially zero and the mutual inductance between each of the first and second primary windings and the load winding is not zero. The systems described are particularly effective in wireless power transfer applications where electromagnetic field exposure as well as the system efficiency may be an issue.
Claims20
A wireless power transfer (WPT) system comprising:
- a first primary winding circuit having a first AC power system (AC1) and first winding (PW1);
- a second primary winding circuit having a second AC power system (AC2) and a second winding (PW2);
- wherein the PW1 and PW2 are spatially positioned with respect to one another where the mutual inductance, M12, between PW1 and PW2 is zero or substantially zero;
- a secondary winding circuit having a load and secondary winding (SW), the SW spatially positioned adjacent to PW1 and PW2 where the mutual inductance between PW1 and SW is not zero and the mutual inductance between PW2 and SW is not zero;
- and, a power control system for controlling input AC power to each of AC1 and AC2.
