| 摘要 |
A power transmitting unit-side resonance circuit including a resonance capacitor (Cr) connected in series to a power transmitting coil (Lp) and a power receiving unit-side resonance circuit including a resonance capacitor (Crs) connected in series to a power receiving coil (Ls) are caused to resonate with each other so that each resonance circuit resonates. With this, power is transmitted between the power transmitting coil (Lp) and the power receiving unit (Ls) making use of magnetic field resonance coupling and electric field resonance coupling. By making use of resonance, only effective power is transmitted from the power transmitting unit side to the power receiving unit side, while reactive power that is reflected is reserved as resonance energy in each resonance circuit. |
