Title:
WIRELESS CHARGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/190225
Kind Code:
A1
Abstract:
A wireless charging device according to one embodiment comprises: an inverter; a switch connected so as to make direct current power inputted to the inverter flow toward a ground after passing a first load resistance or a second load resistance; and a control unit for determining whether the voltage of the direct current power is higher than a reference voltage while connected to the first load resistance or the second load resistance, and selecting guaranteed power corresponding to a load resistance having a low resistance value among the load resistances of which the voltage is higher than the reference voltage, and storing same, wherein the first load resistance can have a resistance value lower than that of the second load resistance.
