Abstract
We propose a contactless power transmission system (CLPS) using new meander-type coils. The main feature of meander-type coil is their effectiveness for stabilizing the amount of the tramsmitted power against the load displacement and electromagnetic noise emission. When the pitch of the transmitter coil corresponds to the receiver shape, the maximum transmitting power was obtained. A new exciting system was realized by means of an easy circuit. The circuit always fixes the relative positions between the transmitter and receiver coils. The system is able to ensure the optional distribution of flux. Therefore, the receiver position can be determined and the pitch of the transmitter coil can be set.
