First Claim
Patent Images
1. A wireless power transmitter, comprising:
- 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 sampler configured to sample points of the carrier frequency signal at the different retrieval sampling points of time,wherein the sampling controller compares values sampled by the sampler with each other, and determines a determined sampling point based on a comparison result.

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.

12. A method for controlling a sampling of a wireless power transmitter, comprising:
-
setting different retrieval sampling points of time for each section among candidate sampling points of time in each section of a carrier frequency signal; sampling points of the carrier frequency signal at the different retrieval sampling points of time; and comparing values sampled by the sampler with each other and determining a determined sampling point based on a comparison result. - View Dependent Claims (13)

14. A wireless power transmitter configured to determine n candidate sampling points of time for sections of a carrier frequency signal, determine one of k retrieval sampling points for each of the candidate sampling points of time, sample the carrier frequency signal based on the selected sampling point of time,
wherein n and k are natural numbers, and n is greater than k.
