<P>PROBLEM TO BE SOLVED: To provide a control method for non-contact feeder system, capable of highly precisely detecting metal foreign matter without changing an exciting frequency of a feeder coil installed at a feeder area and to provide a non-contact feeder system. <P>SOLUTION: When an apparatus E is on a placement surface, a full-bridge circuit is subjected to a full-bridge action to excite a primary coil L1. When the apparatus E is not on the placement surface, the full-bridge circuit is subjected to a half-bridge action to excite the primary coil L1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
