Abstract: 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.

Abstract: An apparatus for both inductive coupled power transferring and electrical-field coupled power transferring is disclosed. The apparatus includes a power converter, a control circuit, a wireless communication receiving circuit, and a metal plate. The power converter receives input voltage and converts the input voltage into specific voltage. The control circuit controls the power converter. The wireless communication receiving circuit receives a power identification signal which is power requirement information coming from a first or second external device. The metal plate is coupled to the power converter. When inductive coupled power transfer mode is executing, the control circuit controls the power converter for outputting magnetic-field electricity to charge the first external device.

Abstract: A wireless power supply system for providing a wireless power adapted for multi remote devices. The wireless power supply system comprises a plurality of primary coils, a wireless communication receiver, and a controller. The wireless communication receiver is used for receiving power requirement information. The controller is used for selecting one of the primary coils to transmit the wireless power in accordance with its internal program. When a specific remote device of the remote devices is disposed to the position of the coils and the specific remote device sends a power identification signal, the wireless communication devices receives the power identification signal, and performs a decode procedure to obtain a decoded power identification signal, and the controller selects a specific primary coil of the primary coils to output a corresponding wireless power to the specific remote device in accordance with the decoded power identification signal.
