Abstract
A wireless power transmitter includes a sampling controller setting different retrieval sampling points of time for each section, among candidate sampling points of time, in each section of a carrier frequency signal; and a sampling unit configured to sample points of the carrier frequency signal at the different retrieval sampling points of time. The sampling controller compares values sampled by the sampling unit with each other, and determines a determined sampling point based on a comparison result.
