In addition, the control part is configured to carry out the proportional plus integral control, by a difference between the second operation result and a target value of the second operation result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric power conversion device","description":"Electric power conversion devices carry out feedback control, so that a difference between a duty ratio and a duty ratio target value may approach zero, while a duty ratio, which becomes the origin of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11482946","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.
