METHOD FOR PREVENT FREQUENCY INTERFERENCE OF WIRELESS POWER TRANSMISSION

摘要

The present invention relates to a wireless power transmission method for preventing frequency interference using antenna current sensing. More particularly, to prevent the generation of signal interference and impact between a wireless power transmission device and another device which uses a frequency adjacent to the frequency range of a power signal transmitted from the wireless power transmission device, a current sensor is attached to the adjacent frequency using device. The operation of the wireless power transmission device is temporally stopped while the flow of a current in the current sensor is recognized. Therefore, the present invention relates to a technique for controlling the operation of the wireless power transmission device according to whether the current sensor detects a current.
