Patent number: 9281119Abstract: A system using a three-coil topology for wireless power transfer is disclosed. The system comprises a primary resonator coupled to a power source, a repeater resonator and a receiver resonator. The primary resonator has a primary coil, and the repeater resonator has a repeater coil adjacent to the primary coil.
