SYSTEM AND METHOD FOR INDUCTIVELY CHARGING BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an inductive charging system for recharging a battery.SOLUTION: A system comprises a charger circuit and a secondary circuit. The secondary circuit includes a feedback mechanism to give feedback to the charger circuit through inductive coupling of a primary coil and a secondary coil. The charger circuit includes a frequency control mechanism for controlling a frequency of electric power applied to the primary coil at least partly in response to the feedback from the feedback mechanism.
