METHOD OF MODULATING WIRELESS POWER TRANSMISSION SIGNAL |
摘要 |
<p>The present invention relates to a wireless power transmission apparatus, which enables bidirectional communication with electronic devices without the implementation of additional elements through the wireless power transmission apparatus modulating a wireless power signal in a frequency modulation scheme in order for a packet to be included, and optimizes transmission speed by selecting a signal having a voltage level indicated by data from among two or more signals having different frequencies as a carrier signal, and modulating the wireless power signal. To this end, the wireless power transmission apparatus according to an embodiment of the present invention includes: a power converting unit for forming a wireless power signal on the basis of a carrier signal; a modulating unit for modulating the wireless power signal in order for a packet to be included in the wireless power signal; and a controller for controlling the modulating unit to modulate the wireless power signal by adjusting a driving frequency of the carrier signal, and the power converting unit for the modulated wireless power signal to be transmitted to a wireless power reception apparatus, wherein the adjusting of the driving frequency can be performed by selecting a signal having a frequency corresponding to data included in the packet from among the two or more signals having different frequencies as the carrier signal.</p> |
