The phase of a voltage supplied to a power transmitting coil and the phase of a current that flows in the power transmitting coil or a power receiving coil is detected and the resonant frequency of the power transmitting coil or the power receiving coil is varied such that the phase difference between them becomes a target value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resonant frequency control method, electric power transmitting device, electric power receiving device in magnetic resonant type power transmission system","description":"In a resonant frequency control method in a magnetic field resonant coupling type power transmission system transmitting an electric power from a power transmitting coil to a power receiving coil usin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634493","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.
