The voltage controlled active semiconductor device includes a switching device including a control terminal that receives a control voltage such that the switching device conducts the current based on the control voltage; and a voltage controlled circuit coupled to the switching device along a path of the current and having a total effective resistance. The voltage controlled circuit is configured to regulate the current based on the total effective resistance, and change the total effective resistance based on a voltage feedback parameter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and a method to limit inrush current of single phase input in an electric power system","description":"An electric power system includes an input bridge rectifier configured to convert an AC voltage to a DC voltage; a DC capacitor configured to charge to an DC output voltage based on the DC voltage; an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10491135","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.
