Wired-wireless combined power transmission apparatus and the method using the same

摘要

Disclosed are a wired-wireless combined power transmission apparatus and a method using the same. The wired-wireless combined power transmission apparatus includes a rectifying unit converting an AC input signal into a DC signal, a transformer unit transforming a size of the input signal, which has been converted into the DC signal, into a predetermined size, a wireless power transmission unit receiving the signal transformed by the transformer unit to wirelessly transmit power, and a wired power supply unit receiving the signal transformed by the transformer unit to supply power through a cable. The advantages and disadvantages of the wired power transmission apparatus and the wireless power transmission apparatus are supplemented to each other, so that the power conversion efficiency and the versatility are improved.
