The alternating-current input voltage Vi is converted directly into a direct-current output voltage Vo, with both a forward voltage and a flyback voltage extracted from the secondary winding 12. The converter 1 further has a switch 200 switching the number of turns of the primary winding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AC/DC converter extracting a forward voltage and a flyback voltage from the secondary winding","description":"An AC-DC converter 1 has, e.g.: a primary winding 11 to which an alternating-current input voltage Vi is applied; a secondary winding 12 magnetically coupled with the primary winding 11; a bidirection","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10541621","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.
