The system also includes a receiver (typically installed in the device requiring recharging) that has a flat, planar secondary coil in which an AC current is induced when placed in close proximity (1-3 cm) to the primary coil, a full-wave bridge rectifier to rectify the AC current to DC, and a voltage regulator connected to the rectifier to provide a steady DC voltage required by the charging circuit to charge the mobile device. Power is transmitted from the transmitter to the receiver by magnetic inductive coupling."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-element portable wireless charging device and method","description":"The multi-element portable wireless charging device includes a transmitter having a DC power source (battery), an oscillator connected to the battery for converting the DC to AC, a power amplifier con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9614396","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.
