The converter converts single-phase AC power to DC power and DC power to single-phase AC power and maintains a selected voltage on the DC bus. The converter has an active rectifier and a controller that drives the rectifier with a pulse width modulation according to a switching scheme that switches the rectifier according to an adaptive hysteresis control to maintain constant switching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage doubling variable frequency drive","description":"Briefly, a voltage doubling variable frequency drive includes an active converter connected to a DC bus that is connected to a first inverter that converts DC power to variable frequency, three-phase ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12009756","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.
