Title:
電力を無線で伝送するためのシステム
Document Type and Number:
Japanese Patent JP6857735
Kind Code:
B2
Abstract:
An embodiment of the present invention provides a system (100) for wirelessly transferring electrical power to an electrical load (115) comprising: a feeding device (105) and a device to be fed (110) physically separate and independent from the feeding device; wherein the device to be fed (110) comprises: the electrical load to be fed, a control circuit (125) adapted for generating a clock signal, and a receiving apparatus (120) of the electrical power connected to the electrical load (115); and wherein the feeding device (105) comprises at least one transmission group (135) of the electrical power that includes: a transmitting apparatus (145) adapted for making a non-conductive electrical coupling with the receiving apparatus (120) of the device to be fed (110), a signal management circuit (150) adapted for receiving the clock signal generated by the control circuit (125) of the device to be fed (110) and for generating a pilot signal having a frequency proportional to the frequency of the clock signal, and a power circuit (155) adapted for receiving the pilot signal generated by the signal management circuit (150) and for applying to the transmitting apparatus (145) a voltage wave that is periodically variable over time with a frequency equal to the frequency of the pilot signal.
