Abstract
A contactless power feeder including multiple feed lines includes a coupler disposed between a first feed line and a second feed line adjacent to each other and holding a first section and a second section of each of the first feed line and the second feed line facing each other. The first feed line and the second feed line are arranged in the coupler to cause a direction of a current through the first section of the second feed line relative to a direction of a current through the first section of the first feed line to be opposite to a direction of a current through the second section of the second feed line relative to a direction of a current through the second section of the first feed line.
Claims7
A contactless power feeder for supplying power contactlessly to a power receiver included in a movable body, the contactless power feeder comprising:
- a plurality of feed lines aligned along a travel path for the movable body, the plurality of feed lines comprising a first feed line and a second feed line adjacent to the first feed line along the travel path;
- a plurality of power supplies each connected to a corresponding feed line of the plurality of feed lines to supply alternating current to the corresponding feed line;
- a plurality of power feeding systems aligned along the travel path, the plurality of power feeding systems including a first power feeding system formed as a closed circuit comprising the first feed line that is one of the plurality of feed lines and a first power supply that is one of the plurality of power supplies and a second power feeding system formed as a closed circuit comprising the second feed line that is one of the plurality of feed lines and a second power supply that is one of the plurality of power supplies;
- and
- a coupler disposed between the first feed line and the second feed line and holding the first feed line and the second feed line, the coupler holding a first section and a second section of each of the first feed line and the second feed line facing each other, and
- wherein the first feed line and the second feed line are arranged in the coupler to cause a direction of a current through the first section of the second feed line relative to a direction of a current through the first section of the first feed line to be opposite to a direction of a current through the second section of the second feed line relative to a direction of a current through the second section of the first feed line.
