PROBLEM TO BE SOLVED: To provide a non-contact feeder system, capable of turning off the power for a carrier vehicle on a track without having to the power supply to the primary feeder. SOLUTION: When a magnetic field is generated around the primary feeder 1 by a high-frequency power supply, voltage is induced at a secondary pickup coil 2. The induced voltage is rectified by a rectifier circuit 4 to generate desired DC power in constant-voltage circuit 5 and output it as the power for the carrier vehicle. To the output of the rectifier circuit 4, a thyristor 60 is connected. When the thyristor 60 is turned on, the output of the rectifier circuit 4 is short- circuited. As a result, the output voltage of the constant-voltage circuit 5 becomes 0 V, and the power for the carrier vehicle is turned off.
