Resonant charging works by creating a wireless transfer of electrical energy between two coils, tuned to resonate at the same frequency. Based on the principles of electromagnetic coupling, resonant-based chargers inject an oscillating current into a highly resonant coil to create an oscillating electromagnetic field. A second coil with the same resonant frequency receives power from the electromagnetic field and converts it back into an electrical current that can be used to power and charge devices.
Based on the specialized technology of WirelessPower21, electric field is minimized and electric power is transmitted only by magnetic field, satisfying regulatory standards and providing stable wireless power integration solution.
Transmitter (Tx) resonance freq. = Receiver (Rx) resonance
Transfer power wirelessly where wired power can not be transferred
. Underwater, Water-surface, Underground
. Rotating object
. Harsh environments (High speed/pressure/humidity)
Simultaneously multiple charging (1:N)Increasing transfer distance (VS induction)
Broaden transferrable area using Repeaters
. Total Efficiency
= Eff. btw coils(ηC) x Tx Circuit Eff.(ηT) x Rx Circuit Eff. (ηR)
. Tx Circuit Eff. > 80%, Rx Circuit >90%
. Efficiency between coils is the main factor for total efficiency
. Efficient Transfer Distance = Coil size
. Repeater merit: broaden transferable(charging) area
. Each Repeaters loss: Less 2%
