<P>PROBLEM TO BE SOLVED: To provide a non-contact power transmitter which can be easily designed (manufactured). <P>SOLUTION: The non-contact power transmitter 10 includes: an AC power supply 11, a resonance system 12 for contactlessly transmitting power supplied from the AC power supply 11, and a load 17 connected to a secondary coil 16 of the resonance system 12. The resonance system 12 has a primary coil 13 connected to the AC power supply 11, a primary side resonance coil 14, a secondary side resonance coil 15 and the secondary coil 16. The resonance system 12 is configured so that when the relation between input impedance and a frequency in the resonance system 12 is graphed, the impedance is while having a maximum point Pmax and a minimum point Pmin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
