Title:
CONTACTLESS POWER FEEDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/063570
Kind Code:
A1
Abstract:
A contactless power feeding apparatus is provided with a secondary winding to which power is supplied from a primary winding by an AC power supply. The impedance absolute-value characteristic of Z1 with respect to the frequency has the frequency of the fundamental wave component thereof to be between a frequency where the local maximum exists and that is nearest to the frequency of the fundamental wave component of the AC power supply, and a frequency where the local minimum exists and that is nearest to the frequency of the fundamental wave component. The impedance absolute-value characteristic of Z2 with respect to the frequency has the frequency of the fundamental wave component thereof to be between a frequency where the local maximum exists and that is nearest to the frequency of the fundamental wave component of the AC power supply, and a frequency where the local minimum exists and that is nearest to the frequency of the fundamental wave component. In the above-mentioned sentence, Z1 indicates the impedance of just the primary side when viewed from the output side of the AC power supply, and Z2 indicates the impedance of just the secondary side when viewed from the side of a load to be connected to the secondary winding.
