The output voltage can be both constant and adjustable, so that the output changes with the phase angle information of input, and also provides the chopping wave structure with current for proper functioning. The device is applicable for bigger power range with better compatibility and stronger adaptability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Constant-voltage drive device capable of adjusting output voltage","description":"A constant-voltage drive device capable of adjusting output voltage includes a chopping wave structure, an AC power voltage detection module, an AC voltage signal bias module, a power factor correctio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9735668","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.
