The operation mode setting part also may set a ratio of a switching active period Tact, in which the main switching element is caused to perform switching operations, to a switching stop period Tstop, in which the switching operations are stopped, in the case of the burst mode operation in accordance with the detected input power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power-supply device","description":"A switching power-supply device includes an input power detecting part that finds a DC input power from a detected DC input voltage and a detected DC input current, and an operation mode setting part ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9831786","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.
