The input current of the power converter is measured within each cycle-by-cycle, i.e. within each cycle of an external clock reference and the charge current is reduced if the input current exceeds a defined portion, e.g. 80% of the maximum allowable input current. The power converter may only enter current limited operation after the charge current has been already reduced to zero. Operating out of current limit mode ensures a maximum efficiency of the converter, maximize the current deliverable to a given load and minimizes subharmonics in the output current and voltage, thereby minimizing interference with other system component."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge current reduction for current limited switched power supply","description":"Circuits and methods for a switched power converter providing charge power for at least one battery and at the same time delivering current to operate an electronic device, wherein the converter is en","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8513920","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.
