Abstract: The present disclosure discloses a wireless power transfer device. A power transmitting coil (or a power receiving coil) is equally divided into N equivalents by configuring a primary-side compensation capacitor (or a secondary side compensation capacitor) to comprise N sub-compensation capacitors which are connected in the power transmitting coil (or the power receiving coil) in an equally distributed manner. With the distributed capacitance connection structure, it is possible to reduce the voltage across each coil segment of the power transmitting coil (or the power receiving coil), thereby reducing the coil-to-ground common mode current of the transmitting coil and the circulating current caused by the receiving coil.
