POWER RECEVING DEVICE FOR WIRELESS CHARGING AND PORTABLE ELECTRONIC DEVICE HAVING THE SAME

摘要

PURPOSE: A power receiving device for a wireless charging process and a portable electronic device including the same are provided to replace only a part for receiving power provided from a power supply device for the wireless charging process, thereby reducing maintenance costs. CONSTITUTION: A power supply device(100) generates charging power to be supplied to a power receiving device. The power receiving device includes a portable electronic device which includes a battery. The power supply device an power receiving device include a primary coil(110) and a secondary coil(210) which are corresponded each other. The primary coil and secondary coil are mutually coupled by induction combining. The power supply device includes a charging power supply circuit(150) for generating a magnetic field.
