Abstract
The present invention relates to a near-field wireless power transfer system capable of having a constant efficiency regardless of a charging position of a receiver by only using a simple impedance matching circuit without using a separate existing complex adaptive impedance matching circuit or a control circuit, and simultaneously transmitting power without having difficulty with impedance matching even for wireless power transmission to a plurality of electronic devices by applying a structure having a uniform mutual inductance between a wireless power transmitter and a wireless power receiver.
