发明名称 NON-CONTACT CHARGER
摘要 <p>PROBLEM TO BE SOLVED: To provide a non-contact charger which enables to shut off the power supply of a charging charger after the completion of charging, etc., and to issue an alarm when the charging charger emits an abnormal flux by observing the change of magnetic field (flux density) which occurs in the charging charger of a non-contact charger following the change of the absorbed amount of the magnetic field by a charged charger, and which provides a compact, light charged charger, being capable of finishing the charge for a short period. SOLUTION: In a non-contact charger made up of two chargers, i.e., a charging charger 2, which converts power obtained from an AC power supply 24 to electromagnetic force and outputs it, and a charged charger 1, which receives and converts the electromagnetic force outputted from the charging charger 2 into charging power, and three means are provided. A magnetic field detecting means 21, which detects flux density generated from the charging charger 2 side, a calculating means 25, which calculates the flux detected by the magnetic field detecting means 21, and a feeding- back means 23, which feeds back the result of the calculation by the calculating means 25 to the charging charger 2 for controlling a charging current. Additionally, an alarming means 26 is provided for issuing an alarm, when the magnetic field detecting means 21 detects an abnormal amount in the flux.</p>
