DC-DC voltage transformation and isolation are provided in a first power conversion stage, the first stage having a CA input for receiving power from the source and a CA output for delivering a galvanically isolated unregulated AC adapter module (UAAM) voltage. First stage circuitry for performing the first power conversion stage is provided in a self-contained adapter module having input terminals for connection to the AC source and an output connected to the CA output for providing power to a second power conversion stage wherein the second power conversion stage is external to the adapter module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Universal AC adaptor","description":"Power from an AC source at a source voltage is converted for delivery to a load at a DC load voltage, where the source voltage may vary between a high line voltage and a low line voltage in a normal o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462527","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.
