摘要

An electronic device is provided. The electronic device includes a coil unit, a power transmission circuit electrically connected to the coil unit, and a control circuit configured to wirelessly transmit power using the coil unit, and the coil unit may include a first coil. The first coil may include a first layer wound in a first shape by a first number of turns, and a second layer extending from the first layer and wound in a second shape by a second number of turns, and the second layer may be disposed above the first layer to overlap the first layer.

說明書

According to an embodiment, the outer diameter D5 of the fifth layer 231 may be larger than the outer diameter D6 of the sixth layer 232, and the inner diameter d5 of the fifth layer 231 may be larger than the inner diameter d6 of the sixth layer 232. The central axis O″ of the fifth layer 231 and the central axis O″ of the sixth layer 232 are arranged on the same line, and the region adjacent to the inner diameter d5 of the fifth layer 231 may be disposed to overlap the region adjacent to the inner diameter d6 of the sixth layer 232. As another example, the central axis O″ of the fifth layer 231 and the central axis O″ of the sixth layer 232 are arranged parallel to each other within a specified distance depending on a design tolerance. According to an embodiment, the first layer 211 and the second layer 212 may be disposed on the same line or may be disposed parallel to each other within a predetermined distance with reference to the central axis O, and the third layer 221 and the fourth layer 222 may be disposed on the same line or may be disposed parallel to each other within a predetermined distance with reference to the central axis O′.
