WIRELESS POWER SYSTEM AND WIRELESS POWER CONTROL METHOD FOR PROVIDING TWO CHARGING MODES TO INCREASE ENERGY CHARGING EFFICIENCY THROUGH FEEDBACK

摘要

Disclosed are a wireless power system which provides two charging modes to increase energy charging efficiency through feedback and a wireless power control method thereof. In the wireless power system configured to be a pair of transmission devices wirelessly transmitting energy and a receiving device charging energy, the receiving device includes: load resistance used to wirelessly charge the energy; a controller measuring a magnitude of the load resistance and determining one between a series circuit structure and a parallel circuit structure as a structure for wirelessly charging the energy transmitted from the transmitting device based on the magnitude of the measured load resistance; and at least one switch providing a switching to the circuit structure corresponding to a determination of the controller.;COPYRIGHT KIPO 2019
