The voltage regulator is coupled to a switch and generates a direct current (DC) voltage signal. The coupled inductor device of the sensing block comprises a pull-down resistor, wherein the coupled inductor device is configured to convert a voltage signal of the neutral wire to a 180-degree phase-shifted voltage signal of the neutral wire and generate a reference voltage signal using the pull-down resistor. The voltage sense amplifier is configured to amplify a voltage gap between the 180-degree phase-shifted voltage signal of the neutral wire and the reference voltage signal. The sensing block detects a phantom voltage on the one of three phase wires and provides an output signal corresponding the secondary power source during a blackout period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power blackout sensing system with a phantom voltage detector including a coupled inductor device","description":"A power blackout sensing system includes: a voltage regulator configured to receive one of three phase wires and a neutral wire of a primary power source that provides an alternating current (AC) powe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505390","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.
