A determination is made as to whether the input voltage DCV in a first frequency range determined by a resonant frequency of a series resonance circuit of the power transmission device and parallel resonance circuit of the power receiving device falls with a range of 25 mV to 450 mV, and the input voltage DCV detected in a second frequency range is equal to or lower than 100 mv. When the results of both determinations are true, power is transmitted to the power receiving device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power transmission device, wireless power transmission system, and power transmission determination method","description":"The frequency of an AC voltage applied to an active electrode and a passive electrode of a power transmission device is swept and input impedance (input voltage DCV) of a power receiving device side a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800093","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.
