The integrated circuit uses each factor to control a secondary switching element to perform synchronous rectification. In some examples, the flyback converter includes an auxiliary winding at the primary side of the transformer and a knee point voltage detection unit. The knee point voltage detection unit is configured to determine, based on an analog input indicative of a voltage at the auxiliary winding, an integral of value and detect, based on the integral value, a knee point voltage associated with the voltage at the auxiliary winding. A controller may use the detected knee point to control a primary side switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controlling components of power converters using delta-sigma modulation on analog inputs","description":"A flyback converter is described that in some examples includes an integrated circuit that includes a delta-sigma converter and a cascaded integrator-comb filter configured to determine: a proportiona","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837915","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.
