With magnetic field coupling WPT, multiple mobile objects can be fed electric power, and be operated simultaneously because the feeding coil generates symmetrical magnetic fields. It has been reported that the wireless power transmission distance can be extended by loading an impedance element on the coils and inserting a relay coil between the transmission coil and the received coil. This study evaluated the effectiveness of the loaded impedance in the case where receiving coils were placed on both sides of the feeding coil by electromagnetic field analysis. Wireless power transmission efficiencies are calculated when impedance is varied at 2 MHz in the case that the distances from the feeding coil to the received coils were 75 mm. The efficiency became high when the loaded reactance for the feeding coil was equal to 30 Ω and the load reactance for the received coils were equal to 60 Ω. By using reactance load, the wireless power transmission efficiency with the distance of 75 mm was almost the same as that with the distance of 10 mm. |
