摘要： An exemplary wireless power transmitter may comprise: a transmission coil; a converter configured to output a driving voltage; an inverter configured to output AC power to the transmission coil by using the driving voltage; and a controller. The controller may be configured to identify a first voltage at one point inside the wireless power transmitter while wirelessly transmitting power through the transmission coil. The controller may be configured to, on the basis that a peak-to-peak value identified according to the first voltage exceeds a first reference value, perform at least one operation for providing, to a wireless power receiver, a first packet for reducing a modulation depth of the wireless power receiver.
