WIRELESS POWER SUPPLY DEVICE AND METHOD
First Claim
1. A wireless power supplying device for supplying power to a receiver having a magneto-electric conversion function by means of electromagnetic induction, characterized by comprising a control part and at least one transmitting part connected to the control part, wherein the control part includes a control circuit and a power supply module;
- wherein, the control circuit is used to determine a power requirement of each transmitting part connected to the control part, and control the power supply module to send an electrical signal satisfying the power requirement to the transmitting part, and the transmitting part in turn generates a magnetic field based on the electrical signal and supplies power to a load of the receiver.

Abstract
There is provided a wireless power supplying device and method. The device includes a control part and at least one transmitting part connected with the control part. The control part includes a control circuit and a power supply module. The control circuit is used to determine the power requirement of the transmitting part connected with the control part and control the power supply module to transmit an electrical signal satisfying the power requirement to the transmitting part. The transmitting part generates a magnetic field based on the electrical signal and supplies power to a load of a receiver. The wireless power supply device and method enable each coil to generate electromagnetic induction with desired power, to supply power for the receiver reasonably, and reduce the number and the complexity of the transmitting part.
