Abstract
Disclosed are a method and an apparatus for transmitting power wirelessly. The apparatus for wirelessly transmitting power includes: a power converter including an inverter for converting DC power into AC power, a resonance circuit, and two sensors for extracting a message transmitted from a receiving apparatus receiving power through magnetic induction of the resonance circuit; and a controller for controlling an operation of the inverter by selectively using messages extracted by the two sensors. When the controller fails in decoding the message extracted by one of the two sensors, the controller decodes the message extracted by the other of the two sensors and controls the operation of the inverter based on the decoded message. One of the two sensors is connected to a front stage of the inverter and the other of the two sensors is connected to a rear stage of the inverter.
