The control device adds a zero-phase component Vo common to the three phases to a basic command Vx* for each phase to generate a voltage command V*. The zero-phase component Vo is generated by applying an amplitude a calculated based on the phase and the voltage amplitude to reference zero-phase voltage Voo that has been set, thereby reducing a peak of the voltage command V* for each single-phase inverter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-phase power conversion device","description":"A three-phase power conversion device includes: single-phase inverters having AC output ends connected in series to the respective phases of the three-phase AC lines; a control device for performing P","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9595887","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.
