ELECTRIC DEVICE FOR WIRELESS CHARGING

摘要

PURPOSE: A wireless charging type electric device is provided to prevent unnecessary magnetic fields from the time after a secondary battery is charged to the time when a wireless charging type electric device is recharged. CONSTITUTION: An inverter(120) converts rectified DC(Direct Current) power into AC(Alternating Current) power. An inverter control circuit(140) controls the inverter. An electric double layer capacitor(150) supplies power to the inverter control circuit. A secondary battery(240) supplies power to an electric motor. A signal generating circuit(260) generates a high frequency signal in which a command is modulated by a charging voltage of the secondary battery. A charging circuit(220) charges the secondary battery.
