A method includes determining a desired charging voltage to charge a rechargeable storage unit, switchably controlling a charging converter to step up the input voltage if an input voltage is lower than the desired charging voltage to generate a charging voltage, and switchably controlling the charging converter to step down the input voltage if the input voltage is higher than the desired charging voltage to generate the charging voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for a switching power converter","description":"A charging converter includes a plurality of switches configured to switchably operate to either step up an input voltage or step down the input voltage and generate a charging voltage on a second ter","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9673638","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.
