Abstract
One embodiment of the present invention can provide: a wireless power transfer system which can reduce the error of the output voltage of a DC-DC transformer, and at the same time, change the magnitude of the output voltage according to the power transfer method and efficiency; and a wireless power transfer system which can variably control an output control port in a control part, and thus actively control the output of the DC-DC transformer regardless of the characteristics of the DC-DC transformer.
