ELECTRONIC DEVICE FOR WIRELESSLY TRANSMITTING POWER OR WIRELESSLY RECEIVING POWER, AND OPERATING METHOD THEREFOR

WIPO Patent Application WO/2022/164194

A1

According to various embodiments, an electronic device comprises: a first coil wound in a first winding direction; a second coil arranged on the inside of the first coil so as to be wound in a second winding direction differing from the first winding direction; and a power conversion circuit connected to the first coil and the second coil to rectify and output a first inductive power induced from the first coil or a second inductive power induced from the second coil, or output charged power to the first coil or the second coil by using a driving power inputted from the outside, wherein the power conversion circuit comprises: a first switch group to which one end of the first coil and one end of the second coil are connected; a second switch group to which the other end of the first coil is connected; and a third switch group to which the other end of the second coil is connected, the first switch group and the second switch group constitute a first full bridge circuit, and the first switch group and the third switch group can constitute a second full bridge circuit. Other various embodiments are possible.
