NON-CONTACT FEEDER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technique which can get sufficient output voltage even in case that a load has changed, concerning a non-contact feeder system. SOLUTION: In a separate transformer 4, a primary coil 4a and a secondary coil 4b are arranged apart without contact. In the secondary coil 4b, AC voltage is generated by magnetic induction which arises when the primary coil 4a is supplied with AC voltage, and a resonant capacitor 5 is connected in parallel. A doubled current rectifying circuit 6 converts AC voltage generated in the secondary coil 4b into DC output voltage Eo, and supplies it to a load resisting element 7. Furthermore, a resonant circuit is composed of an exciting inductor in the separate transformer 4, a leak inductor made by magnetic induction, and the resonant capacitor 5.
