On the inner circumferential surface sides of the coils of the power-supplying resonator and the power-receiving resonator, cylindrical magnetic members and which cover the entire inner circumferential surfaces of the coil of the power-supplying resonator and the coil of the power-receiving resonator are arranged. When power transmission between the power-supplying resonator and the power-receiving resonator is performed, while varying the magnetic field, magnetic field occurring around the power-supplying resonator and the power-receiving resonator is shielded by the magnetic members. This improves power transmission efficiency of power transmitted from the power-supplying module to the power-receiving module, as compared with a case of arranging no magnetic members."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power transmission apparatus","description":"A power-supplying module and a power-receiving module are positioned so that a coil surface of a power-supplying resonator in the power-supplying module and a coil surface of a power-receiving resonat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9755698","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
