Abstract

We propose a contactless power transmission system using a new meander type coil. Effectiveness for stabilizing the amount of the transmitted power against a load displacement and suppressing electromagnetic noise emission is the features of meander type coils. Maximum power is transmitted when the pitch of the transmitter coil corresponds to the receiver shape. An Active Excitation System was realized using circuit in which the relative position between transmitter and receiver coils are always assured. Furthermore the system result is an optimal distribution of flux. Therefore, the receiver position is cleared and transmitter-pitch is set up optimally
