The magnetic amplifier includes one or more magnetic cores which provides a controllable reluctance for magnetic flux. The magnetic amplifier includes one or more power windings which receive energy from an alternating current (AC) supply (e.g., AC mains) and delivers rectified AC current as direct current (DC) to one or more solid-state light sources. The magnetic amplifier includes one or more control windings coupled to a DC control source. The drive circuit may have two or more rectifiers (e.g., solid-state rectifiers) to provide a direct current to drive the solid-state light sources and also to isolate the one or more control windings from interference from the magnetic flux of the one or more power windings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High efficiency power controller for luminaire","description":"Systems, methods and articles for providing lighting or illumination systems having drive circuits that employ a magnetic amplifier (“mag-amp”) and one or more feedback circuits to form a power conver","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9781797","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.
