The controller also includes a means for determining a ratio of an input voltage sense signal to an output voltage sense signal and for generating an input charge control signal responsive to the input charge signal and the ratio of the input voltage sense signal to the output voltage sense signal. A means for comparing the input charge control signal to the delayed ramp signal to generate a drive signal to control a switch of the power supply is also included."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Single-stage power supply with power factor correction and constant current output","description":"An example controller for providing power factor correction and a constant current output in a power supply includes a means for generating a delayed ramp signal and a means for integrating an input c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537582","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.
