Many engineers have recently been developing battery chargers that have employed contactless power transmission techniques for consumer products. These have contributed to improving the convenience of charging batteries. We investigated methods of electromagnetic induction for transmission from several different types. The efficiency of power transmission was dependent on the quality factors of two coils and the coupling coefficient between them. Previous reports indicated that copper clad aluminum wire (CCAW) and magnetic-plated wire (MPW) can improve quality factors. We need to select these materials appropriately according to our individual needs in order to achieve highly efficient power transmission systems. Therefore, we examined the performance of three materials for power transmission coils in this research and found a method of selecting materials to construct a highly efficient system of transmission with a broad range of coupling coefficients.

Cross coils that operate in an alternating magnetic field are proposed for transmitting signals. They cancel the noise induced by a symmetric magnetic field stem from a transcutaneous power-transmitting coil, and then transmit and detect the signals in the magnetic field. In comparison with figure-of-eight coils, cross coils keep a certain senditivity due to dislocation between the transmitting and detecting coils. The signal-transmitting ability of cross coils is not very high, but above properties make them useful as transcutaneous signal-transmitting coils.

The Contactless Power Station (CLPS) is a cordless power supply system that makes use of electromagnetic induction generated by means of coils. We propose a desktop design for CLPS, using spiral coils, because it is convenient to be able to charge the batteries of a digital still camera, a cellular phone, and a PC on single desk. The primary coil are arranged so that the coupling factor becomes 0, since it is inconvenient for the primary coils to be excited by each other. However, when the primary coils are synchronized and driven, the magnetic flux interferes with the electric power transmission. Attention was paid to changing each phase on the primary coils. As a result, when the phase was moved, stabilization of the output voltage was confirmed. Therefore, if the primary coils are suitably arranged, the power transmission pad can stabilize electric power transmission everywhere.
