The primary winding comprises a first winding portion (np1) and at least one further winding portion (np2); and the switch based circuitry comprises controllable switches (Q11, Q41, Q12, Q42, Q21, Q31) capable of switching between a first operation state wherein the input voltage is connected only over the first winding portion and at least a second operation state wherein the input voltage is connected over the first and the at least one further winding portions, thereby enabling switching between two different transformer ratios (n1, n2)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switched mode power supply and method of operating a switched mode power supply","description":"A switched mode power supply comprises a switched mode converter (12) and a controller for controlling the switched mode converter, wherein the switched mode converter is provided for converting an in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621052","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.
