In a first operation mode, the boosted vol tage is applied to the two ends of the first capacitor when a positive voltage is input, and applied to the two ends of the second capacitor when a negative voltage is input. In a second operation mode, the boosted voltage is applied to two ends of the first and second capacitors connected in series. Thus, there is provided a power factor correction circuit which has a high efficiency and is compatible with an input voltage in a broad range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power factor correction circuit and power supply device","description":"A power factor correction circuit includes: a coil and MOSFETs that boost an input voltage to generate a boosted voltage; a first capacitor having one end connected to a first output terminal, and the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793793","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.
