Abstract:
A power transmission apparatus includes capacitors connected in series between an active electrode and a passive electrode. A power reception apparatus includes capacitors connected in series between an active electrode and a passive electrode. When a capacitance between the active electrodes is represented by Caa, a capacitance between the passive electrodes is represented by Cpp, and reactances of the capacitors are represented by X1, X2, X3, and X4; the active electrodes, the passive electrodes and the capacitors are configured such that Cpp/Caa=X1/X2=X3/X4 and Cpp≧Caa are satisfied. Thus, a wireless power transmission system capable of stabilizing an operation of a load circuit in the power reception apparatus is provided.
