An ECU controls a converter such that an input impedance of the converter attains a prescribed value in the first control region and controls the converter such that received electric power becomes close to a target by changing the input impedance in the second control region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contactless power transfer system","description":"A power supply ECU controls a converter to have a first control region in which a voltage is raised as a coupling coefficient is larger, and a second control region in which the voltage is maintained ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825473","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.
