A commutation current is shared between all of the switches, and a resonance is induced in the boosting resonant circuit by controlling each of the synchronous rectifier switches to turn off at a time prior to a turn-off time for a corresponding one of the switches operating under ZVS conditions, wherein the primary current is boosted above a minimum commutation value during ZVS periods. The ZVS switches are further driven with a constant dead time, and the synchronous rectifier switches are driven to provide a fixed time relation with respect to all of the switches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Commutation current steering method in a zero volt switching power converter using a synchronous rectifier","description":"A commutation current steering method is provided for a power converter having an isolation transformer, a plurality of primary ZVS switches, a plurality of secondary switches for synchronous rectific","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837920","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.
