WIRELESS POWER CONTROL SYSTEM

Japanese Patent JP2018074903

A

PROBLEM TO BE SOLVED: To provide a wireless power control system.SOLUTION: A wireless power transfer component is provided that has a selectively adjustable resonator circuit having a Q control sub-circuit which varies the Q factor of the resonator circuit to control an amount of power relayed by the resonator circuit. The resonator circuit may have wireless power supply, a wireless power receiver, an intermediate resonator or any combination thereof. The resonator circuit may be actively configured on the basis of a feedback circuit. The feedback circuit may sense a characteristic in a secondary circuit or elsewhere and actively operate the control sub-circuit on the basis of the sensed characteristic. The feedback circuit may cause the Q control sub-circuit to change (reduce or increase) the Q factor when the sensed characteristic crosses a threshold value. The Q control sub-circuit may include a variable resistor having a value that can be varied to adjust the Q factor of the resonator circuit.SELECTED DRAWING: Figure 2
