Some embodiments may provide advantages that a PLC system can supply much more power while reducing a charging period of time of an auxiliary power supply for supplying power with urgency when an abnormality occurs in a power module of the PLC system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PLC system","description":"In some embodiments, a PLC system includes a memory unit configured to back up user data stored in a MCU thereto when the power supply from the power module is interrupted, a capacitor configured to b","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819346","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.
