Abstract: An example wireless power transmitter may include a transistor configured to output an amplified signal, a first capacitor coupled to the transistor in parallel, a first LC resonant circuit coupled to the transistor in parallel, a third capacitor having a first end coupled to an output terminal of the transistor and the first LC resonant circuit, a feeding coil coupled to a second end of the third capacitor in series, and having at least a part configured to form a second LC resonant circuit with the third capacitor, and a transmission resonator including a transmission coil and a fourth capacitor coupled to the transmission coil in series. At least a part of the transmission coil may be magnetically coupled with the feeding coil, and at least a part of power received from the feeding coil may be output to an outside through the transmission resonator.

Abstract: A wireless power transmitter may include a power amplifier configured to output an amplified signal based on an input signal and a driving voltage, a first LC resonant circuit connected in parallel to the power amplifier, a matching circuit, and a transmission coil connected to the matching circuit. The matching circuit may include a second LC resonant circuit including a first inductor and a first capacitor connected in series to the first inductor, and having one end connected to an output terminal of the power amplifier and one end of the first LC resonant circuit, and a second capacitor and a third capacitor respectively connected to the other end of the second LC resonant circuit. The first inductor may be configured to have an inductance value leading to an impedance of the second LC resonant circuit equal to or greater than a first predetermined magnitude at at least one second or higher harmonic frequency of an operating frequency of the input signal.
