Terminal device and wireless power feeding system
First Claim
1. A terminal device, wherein the terminal device is configured in a system, the system includes a power feeding apparatus and a power receiving apparatus, the power receiving apparatus receives an electric power waveform from the power feeding apparatus through a harness, the power feeding apparatus supplies the power receiving apparatus with an electric power by coupling with the power receiving apparatus, and the coupling is conducted by a magnetic field through the harness or an electric field through the harness,the terminal device comprising:
- a power conversion portion connected to a part of the harness; and
a control portion controlling a power conversion state of the power conversion portion,wherein the control portion controls an input impedance of the power conversion portion to be equal to a characteristic impedance of the harness.

Abstract
A terminal device configured in a system is provided. The system includes a power feeding apparatus and a power receiving apparatus. The power receiving apparatus receives an electric power waveform from the power feeding apparatus through a harness. The power feeding apparatus supplies the power receiving apparatus with an electric power by coupling with the power receiving apparatus. The coupling is conducted by a magnetic field through the harness or an electric field through the harness. The terminal device includes a power conversion portion and a control portion. The power conversion portion is connected to a part of the harness. The control portion controls a power conversion state of the power conversion portion. The control portion controls an input impedance of the power conversion portion to be equal to a characteristic impedance of the harness.
