A current probe measures the magnitude signal of the instantaneous source coil current. A voltage probe measures the instantaneous ac driver voltage. A phase detector compares the phase of the instantaneous source coil current and the instantaneous ac driver voltage, and produces a first output signal proportional to the phase difference. A first amplifier compares the magnitude signal and a target signal, and produces an error signal proportional to the difference. A first compensation filter produces the control voltage that determines the ac driver supply voltage. A second amplifier amplifies the first output signal. A second compensation filter produces the control voltage that determines the impedance of a variable element in the source circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for controlling resonant wireless power source","description":"A resonant wireless power system includes a source circuit having a source coil, an ac driver with a first resistance, representing the equivalent output impedance of the ac driver, and a matching net","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722462","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.
