The current through the SR switch is estimated, so that a zero-crossing condition may be detected and used for turning off the SR switch near the optimal point at which zero current is flowing through the SR switch. The current through the SR switch may be estimated based upon a measurement of the current flowing through the SR switch, a measurement of the current flowing out from the secondary side of a transformer in the voltage converter, or a measurement corresponding to the current flowing into the primary side of the transformer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current sensing and zero-cross detection in semi-resonant voltage converters","description":"A resonant or semi-resonant voltage converter includes a synchronous rectification (SR) switch through which a current having a half-cycle sinusoidal-like shape is conducted when the SR switch is acti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837907","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.
