Apparatus for both inductive coupled power transferring and electrical-field coupled power transferring

An apparatus for both inductive coupled power transferring and electrical-field coupled power transferring, for outputting a magnetic-field electricity to charge a first external device when under an inductive coupled power transfer mode, and for outputting an electrical-field electricity to charge a second external device when under an electrical-field coupled power transfer mode, the apparatus comprising:

• a power converter, for receiving an input voltage and converting the input voltage into a specific voltage;
• a control circuit, for controlling the power converter;
• a wireless communication receiving circuit, for receiving a first power identification signal and/or a second power identification signal, wherein the first power identification signal includes power requirement information of the first external device, and the second power identification signal includes power requirement information of the second external device;
• and
• a metal plate, coupled to the power converter;
• wherein when the wireless communication receiving circuit receives the first power identification signal of the first external device, the apparatus for both inductive coupled power transferring and electrical-field coupled power transferring executes the inductive coupled power transfer mode, and the control circuit controls the power converter for outputting the magnetic-field electricity to charge the first external device;
• wherein when the wireless communication receiving circuit receives the second power identification signal of the second external device, the apparatus for both inductive coupled power transferring and electrical-field coupled power transferring executes the electrical-field coupled power transfer mode, and the control circuit controls the power converter for outputting a high frequency and high voltage power to the metal plate, in order to output the electrical-field electricity for charging the second external device.
