Each of the n UPS modules is configured to supply, to the load, a shared current which is 1/n of the load current. The auxiliary UPS module is configured to output, to the load, a counter voltage having a value in accordance with output voltages of the n UPS modules, and thereby to stand by in a state where no current flows between the auxiliary UPS module and the n UPS modules and between the auxiliary UPS module and the load."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Uninterruptible power supply device","description":"An uninterruptible power supply device includes N UPS modules connected in parallel with one another between an AC power supply and a load, a current detector configured to detect a load current, and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10476300","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.
