A gain converter is provided in a preceding stage of a frequency generator for generating a square waveform signal with a duty ratio of 50% and the gain converter has a setting of a nonlinear gain characteristic that cancels nonlinearity in the input-output characteristics of the current resonant converter section. The nonlinear gain characteristic can be a characteristic of continuous gain conversion or discrete gain conversion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control device of a switching power supply","description":"A control section for a current resonant converter section controls a DC output voltage of a current resonant converter section to settle to a target voltage by varying a resonant period between prede","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9729069","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.
