A control signal for controlling a state of a main switch transistor is generated by using the first signal, the second signal, and a current sampling signal of the main switch transistor in the PFC circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Main switch control circuit in power factor correction circuit","description":"A control circuit in a power factor correction (PFC) circuit includes: a multiplier, used for multiplying a voltage sampling signal by a feedback signal, and outputting a first signal; and a waveform ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9692294","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.
