PROBLEM TO BE SOLVED: To downsize a contactless feeder system and suppress a drop in its switching speed. SOLUTION: A power transformer T is composed of a primary feeder line 12 which is connected with a high frequency AC power source 11, and a pickup 17 which includes a core 15 and secondary winding 16 wound on the core. Furthermore, a series resonance circuit 20 is composed of a power transformer T and a resonance capacitor 16 connected in series to the secondary winding. Two feeder units 13, which include pickups 17 and rectifiers 19 connected with them, are connected in series. A constant voltage controller 14 boosts the voltage outputted from the two feeder units 13 connected in series into specified voltage and supplies it to a load 13a. COPYRIGHT: (C)2007,JPO&INPIT
