The control circuit includes: a calculating module used to generate an output current calculating value based on a voltage across the resonant capacitor and a correction signal at an off moment of the high side transistor; a comparing module used to compare the output current calculating value with a burst mode threshold value and generate a burst mode control signal by comparing the output current calculating value with the burst mode threshold value; and a switching control module used to control the resonant converter to work in a burst mode or a normal mode based on the burst mode control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controller and control method used in resonant converters","description":"A control circuit used in a resonant converter with a switching circuit and a resonant circuit is provided, the switching circuit has a high side transistor and a low side transistor, the resonant cir","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11277071","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.
