<P>PROBLEM TO BE SOLVED: To provide a power transmission system capable of supplying electric power to a resonance coil efficiently using an inverter circuit of a full-bridge method. <P>SOLUTION: In the power transmission system, electric power is transmitted to another coil by resonating with the coil through an electromagnetic field, or a resonance coil which receives the electric power from the coil is used. The power transmission system includes: a resonance coil 100 having a first coil part 110 with an open end, a second coil part 120 with an open end, a first tap part 151 provided to one end of the coil part 110, a second tap part 152 provided to one end of the second coil part 120, and a third coil part 130 provided between the first tap part 151 and the second tap part 152; and an inverter circuit 40 of a full-bridge method that supplies electric power to the first tap part and the second tap part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
