NON-CONTACT POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device of which the cost is suppressed.SOLUTION: The non-contact power supply device is configured to supply power to a power receiving coil 30 in a non-contact manner by means of at least magnetic operation. The non-contact power supply device includes: a power transmitting coil 10 that is connected to an AC power source; and a plurality of relay coils which are disposed along a coil surface of the power transmitting coil 10 while being insulated from the power transmitting coil 10. The power transmitting coil 10 sends power to the power receiving coil 30 via the relay coils and mutual inductance between the power transmitting coil 10 and each of the plurality of relay coils is constant.SELECTED DRAWING: Figure 1
