The AF flyback transformer includes a primary winding and a secondary winding, where the primary winding is split into two halves. The switching unit is placed at the high side of the primary winding, and the PWM controller in collocation with the SSR unit drives the switching unit in response to all the required voltage and current sense signals to keep voltage conversion and power delivery safe and efficient within the specifications. The first half of the primary winding can provide the PWM controller with a continuous and steady working voltage supply after startup, thus eliminating the need for the auxiliary winding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flyback converter with no need for the auxiliary winding","description":"Disclosed is an Auxiliary-Free High-Side Driven Secondary-Side Regulated (AF-HSD-SSR) flyback converter, which includes an AC-to-DC rectification unit, an input capacitor, a switching unit, a current-","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762131","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.
