When the second set pulse is disabled, a selector circuit carries out control using critical conduction control to turn on a switching element using a ZCD comparator detecting that the inductor current has reached zero, because of which the peak current does not increase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply circuit and power factor correction circuit","description":"A switching power supply circuit including a phase angle detector circuit detecting a phase angle specified in advance based on a peak hold signal, a continuous conduction control setting circuit hold","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660519","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.
