COIL FOR INDUCTIVE COUPLED POWER TRANSFER AND ELECTRICAL-FIELD COUPLED POWER TRANSFER

摘要

The present invention relates to a coil for inductive coupled power transfer (ICPT) and electrical-field power transfer (ECPT). The structure of the coil includes a flat panel coil. The wire of the flat panel coil, whose shape is explanted, has a specific width. Also, the flat panel coil is winded on a plane surface. In the ICPT mode, the first terminal of the flat panel coil are inputted a first external voltage, and a magnetic field is outputted to charge a first external device through switching a switch which is coupled to the second terminal of the flat panel coil. In the ECPT mode, the second terminal is cut off, and the first terminal of the flat panel coil is inputted a second external voltage. An electrical field is outputted to charge a second external device through controlling the amplitude and frequency of the second external voltage.
