A second switching control circuit operates in response to an alternating-current winding voltage occurring in the second secondary winding, and includes a time constant circuit causing a switch mechanism connected to the control terminal of a rectifier switch element to operate, and a second feedback circuit arranged to detect and feed back the second output voltage to the time constant circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power-supply circuit","description":"A switching power-supply circuit includes a second rectifying/smoothing circuit arranged to generate a second output voltage by rectifying and smoothing the output of a second secondary winding, and t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621048","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.
