Title:
POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/133028
Kind Code:
A1
Abstract:
Power transmission is performed by utilising magnetic field resonance coupling and electric field resonance coupling between a transmitting coil (Lp) and a receiving coil (Ls) by respective resonance achieved by producing resonance of: a transmission device-side resonant circuit including a resonant capacitor (Cr) connected in series with a transmission coil (Lp); and a receiving device-side resonant circuit including a resonant capacitor (Crs) connected in series with a receiving coil (Ls). By utilising the resonance effect, active power only is transmitted from the transmission device side to the receiving device side. Reflected reactive power is saved as resonance energy in the respective resonant circuits on the transmission device side and receiving device side.
