The power receiver converts the high-frequency power into a power reception direct-current power to charge a battery. A power reception control unit in the power receiver detects a state of charge of the battery and generates a power transmission stop signal on the basis of the state of charge of the battery. A resonance modulation circuit in the power receiver changes resonance conditions in response to the power transmission stop signal. An MPU in the power transmitter demodulates the power transmission stop signal based on an electric variable from a power transmission direct-current power supply due to a change in the resonance conditions and stops an operation of supplying the high-frequency power in a transmission power conversion circuit for a predetermined period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power supply system","description":"High-frequency power is supplied from a power transmitter to a power receiver using an electromagnetic resonance phenomenon between the power transmitter and the power receiver.
