The switching power-supply device includes: an error amplifier, which compares the output voltage with a reference voltage and sends an error voltage as a feedback signal to a primary side; a frequency generation circuit, which generates a switching frequency according to the feedback signal; an off timing determination circuit, which determines a timing at which the switching element is turned off, by comparing a signal depending on the feedback signal with a current flowing through the switching element; and a frequency correction circuit, which corrects the switching frequency generated by the frequency generation circuit, according to an on-duty of the switching element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power-supply with switching frequency correction","description":"A switching power-supply device applies a DC voltage to a primary winding of a transformer and performs a switching operation of a switching element connected to a primary winding to generate and outp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9748850","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.
