The frequency controller apparatus includes a controller for changing the transmission frequency during a power transfer, and the controller sets a decrease amount when decreasing the transmission frequency, so that the decrease amount is smaller than an increase amount when the transmission frequency is increased."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power transfer system for wirelessly transferring electric power in noncontact manner by utilizing resonant magnetic field coupling","description":"There is provided a frequency controller apparatus for use in a wireless power transmitter apparatus configured to wirelessly transmit an inputted power from a power transmitting antenna that includes","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9627929","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.
