Abstract
Provided are an apparatus and a method for transmitting wireless power. According to an embodiment of the present invention, a wireless power transmission apparatus includes: a switching block receiving distributed power signals and delivering the power signals as periodical preamble signals that make a detour around a power amplification and transmission block or delivering the power signals to the power amplification and transmission block; the power amplification and transmission block amplifying the power signals and transmitting the power signals to a coil array block; a sensing block detecting the preamble signals on the respective paths that are delivered to the coil array block, and sensing changes in the preamble signals according to whether wireless power receiving apparatuses appear; and a power distribution and control block controlling the switching block according to sensing results to transmit the power signals to the power amplification and transmission block.
