PURPOSE: A load tracking type non-contact power device and a power supply method using the same are provided to minimize the change of an output voltage of the power device by controlling the output device through the selective connection of a plurality of taps. CONSTITUTION: A sealed case includes a cable passing unit with both sides opened. One core(1300) is installed to surround the cable passing unit. The core passes magnetic flux induced by a load current. An output coil(1600) is wounded around the core. The output coil outputs a voltage induced by the magnetic flux. A plurality of taps varies the output voltage by being connected to other point of the output coil. An output unit(1400) is connected to the plurality of taps and outputs the voltage to the outside. A controller(1520) measures the load current. The controller connects the selected one tap and the output unit. The controller controls the voltage outputted to the outside through the output unit.
