Abstract :
Summary form only given. We have already proposed a desk-type contactless power supply (CLPS) using spiral-formed coils. In this system in order to supply electrical power efficiently to portable electric equipment on the desk, the primary coils are embedded into the surface of the desk. Only the coils beneath the secondary coil which is arranged at the bottom of the electric equipment are excited. We improved the configuration of primary and secondary coils and transmitted characteristics of electric supply and charging circuit.
