WIRELESS POWER TRANSFER SYSTEM AND METHOD THEREOF

摘要

A wireless power transfer system and method is provided. The system includes a source coil that is coupled to a power supplying device and a receiver coil that is coupled to a power receiving device. In operation, when the source coil is energized by the power supplying device and the receiver coil is positioned within a predetermined range of distances from the source coil, the receiver coil is inductively coupled to the source coil at a predefined magnetic resonance frequency to wirelessly transfer power from the power supplying device to the power receiving device. The power receiving device measures a voltage level at the receiver coil and sends information pertaining to the voltage level to the power supplying device. The power supplying device adjusts voltage at the source coil based on comparing the voltage level with a predetermined threshold determined for the power receiving device.
