The switching power-supply device includes: a transient state detection circuit, which detects a transient state and outputs a soft-drive instruction signal; and a drive circuit which turns on-and-off the switching element in a soft-drive operation, in which a charging speed of a gate voltage at a time of passing a gate threshold voltage is delayed as compared to a normal operation, in a case where the soft-drive instruction signal is inputted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power-supply device","description":"A switching power-supply device, in which an input power is applied to a primary winding of a transformer, a pulse voltage is induced in a secondary winding of the transformer by turning on and off a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9614448","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.
