The protection circuit includes a detection unit for acquiring a voltage signal based on a power supply bus voltage, and to generate a detection result which indicates undesirable oscillation on the power supply bus voltage. A control unit includes a delay control module connected with the detection unit, and is coupled to the detection unit and for generating a control signal based on the detection result. The delay control module is for outputting a first control signal when undesirable oscillation happens, and outputting a second control signal after a protection period when undesirable oscillation disappears. A switch circuit controlled by the first control signal and the second control signal turns off for the protection period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection circuit, drive system, chip and circuit protection method, and drive method","description":"A linear driving system for LED with high power factor including a rectifying circuit receiving an AC voltage and generating a DC voltage to a power supply bus having a protection circuit coupled ther","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11483910","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.
