Abstract
A power transmitter according to one aspect of the disclosure includes: a power converter that converts a first AC power supplied from an AC power source into a DC power; a first detector that detects an electric current of the DC power; a feedback signal generator that generates a feedback signal based on the electric current of the DC power; and a controller that performs a feedback control on the electric power supplied to a power receiver based on the feedback signal. The feedback signal generator generates a canceling waveform to reduce a ripple caused to the DC power due to zero crossing of a voltage of the first AC power and generates the feedback signal based on the electric current of the DC power and the canceling waveform.
