摘要
The present invention relates to a wireless power transmission system for improving receiver freedom. The wireless power transmission apparatus according to an embodiment includes a power divider for distributing power supplied from a power source, and an amplifying power of the distributed first phase. A first amplifier adjusts the power of the distributed first phase to a second phase, and adjusts the power to the second phase by using a first variable capacitor connected in series with the inductor and a second variable capacitor connected in parallel with the capacitor. A shifter, a second amplifier for amplifying the power amplified to the second phase, and controlling to transmit the power of the amplified first phase and the power of the amplified second phase to a receiving side through different resonance coils. It may include a control unit.
