The node further connects to an output inductor and an output capacitor and controls the current of the output inductor to charge the output capacitor to produce an output voltage VOUT. A virtual ripple current PWM circuit includes a DC reference voltage level unit, an integrator-plus-DC bias voltage eliminator, a phase synthesizer, a dual reference voltage level generator, and a PWM generator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PWM control circuit of a converter and the control method thereof","description":"A PWM control circuit of a power converter includes an upper-bridge element Q1, connected to a lower-bridge element Q2 by a node, which activates by a driver Q1 and Q2 for switching-on and switching-o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8536841","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.
