When open phase is caused, it is possible to output an indication of whether the open phase is caused on the Δ or Y connection side."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Converter device","description":"A converter device includes: a converter circuit unit converting alternating-current voltages from a Δ connection and a Y connection of a twelve-phase rectification transformer, into a direct-current ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742306","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.
