Electric power transmission apparatus, contactless electric power transmission system, and signal generation method

摘要

An electric power transmission apparatus includes a resonance circuit, a first signal generation unit, and a second signal generation unit. The resonance circuit is used for contactless electric power transmission. The first signal generation unit is connected to one end of the resonance circuit, and generates a first high-frequency signal which includes one or more harmonic components using a switching method. The second signal generation unit is connected to the other end of the resonance circuit, and generates a second high-frequency signal which includes a specific harmonic component using the switching method. The first high-frequency signal is input to the one end of the resonance circuit, and the second high-frequency signal is input to the other end of the resonance circuit.
