In this paper, a 120W wireless power transfer (WPT) system is proposed. The proposed system is designed for wirelessly powering car seats. The car seat performs the operation of the heating, the movement and the tilt adjustment by using the wireless power. The main feature of the proposed system is to supply stable wireless power even in an environment where car seats are moving. In order to achieve the object, the proposed system consists of one transmitting resonator and three receiving resonators capable of covering the moving region. Three receiving resonators are connected to three rectifiers, and each rectifier output is coupled to one output port. As a result, the efficiency of the implemented system is more than 55% in the moving range of 30 cm in the horizontal direction at a transmission distance of 2 cm.
