The wireless power supply system includes a relay coil that is coupled with the power transmission coil and the power reception coil using at least a magnetic field, and a relay circuit that is connected to the relay coil and forms a resonant circuit together with the relay coil. When k1 represents a coupling coefficient between the power transmission coil and the power reception coil and k2 represents a coupling coefficient between the power transmission coil and the relay coil, a relationship k1≥k2 holds true."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power supply system and power transmission device thereof","description":"Provided is a wireless power supply system employing a magnetic resonance technique in which high-frequency power is wirelessly supplied from a power transmission device that includes a power transmis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11509168","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.
