The control circuit controls an alternating-current voltage supplied to the transmission-side pad and an alternating-current voltage supplied to the power reception circuit, so that a power factor of the alternating current supplied from the power transmission circuit to the transmission-side pad connected to the transmission-side resonant circuit and direct-current power supplied from the power supply circuit to an on-board battery are respectively set to target values. As a result, change in power factor can be suppressed even when the coupling coefficient of the transmission-side pad and the reception-side pad changes, and predetermined electric power can be transmitted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-contact power supply apparatus","description":"A non-contact power supply apparatus includes a transmission-side pad, a transmission-side resonant circuit, a reception-side pad, a reception-side resonant circuit, a power transmission circuit, a po","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793719","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.
