This paper proposes a wireless power transfer system available to a contactless extension cord function. We researched a system using a two pairs of magnetic-coupled coil connected to series from considering the utilization scene and the problem. By this method, transmitter can transmit to an apparatus with the voltage of the stable same amplitude in high efficiency. In the characteristic estimate, we converted a non-linear practical use circuit into a linear equivalent circuit and built the method that can derive a numerical formula that calculate the output characteristic.
