Zusammenfassung:A power supply device includes a coil unit including at least one primary coil wirelessly transmitting power according to switching frequency for switching input power, and at least one secondary coil spaced apart from the at least one primary coil. A power conversion ratio is determined with respect to the at least one primary coil according to magnetic flux directly received from the at least one primary coil. The power supply device also includes a support unit maintaining a distance between the at least one primary coil and the at least one secondary coil.
