Abstract
A contactless power transfer system can respectively connect multiple conductive coils in parallel between the power source circuit of a transmitting device and the electric load of a receiving device, and can wind the conductive coils in successively alternating directions. Advantages of the contactless power transfer system include the ability to prevent issues related to overheating and excessive power voltages on the conductive coils, which may occur in applications requiring greater working distances between the energizing coil assemblies.
