CONSIDERATION ON CORDLESS POWER-STATION - CONTACTLESS POWER TRANSMISSION-SYSTEM

We suggest the contactless power transmission system ''Cordless Power Station (CLPS)'' that will radiate little noise by making the coil geo metry noise-reducible. The system makes use of electromagnetic inducti on among the coils. So far we have studied the structures of CLPS cons isting of some spiral coils, and found out that CLPS could be small-si zed and thin. The enough amount of power could be transmitted. In this paper me suggest the structure consisting of meander coils (meander t ype), which has allowances in coil displacement and is easy to be set up. We studied the power-transmitting characteristics with various mag netic materials and coil misalignment. We also discussed the efficienc y improvements in the spiral type. Later we make a comparison in chara cteristics between spiral type and meander type.
