A first winding at a primary side of the high-frequency transformer connects with the inverter while a second winding and a third winding of at a secondary side of the high-frequency transformer connect with the first full-bridge rectifier and the second full-bridge rectifier. The selective circuit connects with DC output ports of the first full-bridge rectifier and the second full-bridge rectifier, thereby operationally selecting two serially-connected full-bridge rectifiers or single full-bridge rectifier to output two voltage levels performed as a multi-level output voltage. The filter circuit connects between the selective circuit and a load for filtering harmonics and outputting a DC voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Unidirectional isolated multi-level DC-DC converter and method thereof","description":"A multi-level DC-DC converter device includes an inverter, a 3-winding high-frequency transformer, a first full-bridge rectifier, a second full-bridge rectifier, a selective circuit and a filter circu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825547","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.
