We suggest the contactless power transmission system "Cordless Power Station (CLPS)" that will radiate little noise by making the coil geometry noise-reducible. The system makes use of electromagnetic induction among the coils. So far we have studied the structures of CLPS consisting of some spiral coils, and found out that CLPS could be small-sized and thin. The enough amount of power could be transmitted. In this paper we suggest the structure consisting of meander coils (meander type), which has allowances in coil displacement and is easy to be set up. We studied the power-transmitting characteristics with various magnetic materials and coil misalignment. We also discussed the efficiency improvements in the spiral type. Later we make a comparison in characteristics between spiral type and meander type.
