The bridge rectifier generates a rectified voltage according to a first input voltage and a second input voltage. The first transformer generates an induced voltage according to the rectified voltage. A magnetizing inductor is built in the first transformer. A parasitic capacitor is built in the power switch element. The second transformer generates a control voltage according to a resonant voltage between the magnetizing inductor and the parasitic capacitor. The output stage circuit includes a plurality of discharge paths and generates an output voltage. The discharge paths are selectively enabled or disabled according to the control voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device for eliminating ringing effect","description":"A power supply device for eliminating the ringing effect includes a bridge rectifier, a first transformer, a second transformer, a third transformer, a power switch element, a delay and stabilization ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303216","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.
