METHOD FOR PROCESSING SIGNAL IN HYBRID WIRELESS POWER TRANSMISSION DEVICE WHICH ENABLES TO TRANSMIT MAGNETIC RESONANCE WIRELSS POWER SIGNAL AND INDUCE WIRELESS POWER SIGNAL, AND HYBRID WIRELESS POWER TRANSMISSION DEVICE USING THE SAME

摘要

The present invention relates to a signal processing method in a hybrid wireless power transmission device capable of transmitting a magnetic resonance wireless power signal and an induced wireless power signal, and a hybrid wireless power transmission device using the same. The signal processing method in a hybrid wireless power transmission device comprises; a step of launching a first product sensing signal through an induced power transmission unit and a second product sensing signal through a magnetic resonance power transmission unit alternately; a step of selecting one between the induced power transmission unit and the magnetic resonance power transmission unit based on an induced response signal and a resonance response signal corresponding to the first and second product sensing signals and operating it; and a step of transmitting a wireless power signal through the selected power transmission unit. According to an embodiment of the present invention, a wireless power receiving device of an induced method and a wireless power receiving device of a resonance method can be charged by confirming the type of the wireless power receiving device through an antenna and a transmission coil and transmitting a wireless power signal of the proper method.
