Abstract
According to the present disclosure, a power transmitter includes a first coil configured to wirelessly transmit power to a second coil of a power receiver, a direct current (DC)/alternating current (AC) converter configured to convert DC power into AC power and supply the AC power to the first coil, and a controller configured to perform frequency control for selecting a frequency of the AC power. The controller at least selects the frequency so that the DC power is less than or equal to withstand power of the DC/AC converter regardless of an amount of misalignment of the second coil with respect to the first coil.
