The apparatus includes a power receiving antenna arranged to oppose the power transmitting antenna; a power receiver, and performing rectification and smoothing; and a second resonance capacitor connected between the power receiving antenna and the power receiver, and resonating with the power receiving antenna to pass the power transmission frequency of the power transmitter. The apparatus includes a filter connected between the second resonance capacitor and the power receiver, and reflecting higher harmonics generated by the power receiver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power transmission apparatus for performing non-contact transmission by electromagnetic induction","description":"A wireless power transmission apparatus is provided for performing non-contact transmission of power by electromagnetic induction, and includes a power transmitter performing frequency conversion; a p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787139","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.
