Abstract:
A primary coil circuit of a ground assembly for wirelessly transferring power to a secondary coil includes: a primary coil magnetically coupled to the secondary coil and having a first terminal and a second terminal; a second capacitor having a first terminal and a second terminal connected to the first terminal of the primary coil; a first inductor having a first terminal coupled to a first input terminal of a power source and a second terminal coupled to the first terminal of the second capacitor; and a first capacitor having a first terminal coupled commonly to the second terminal of the first inductor and the first terminal of the second capacitor and a second terminal coupled commonly to the second terminal of the primary coil and a second input terminal of the power source.
