Claim Text:
1. A power transmitting device comprising: a resonance circuit used in non-contact power transmission; a first signal generating unit connected to one end of the resonance circuit, and configured to generate, with the use of a switching system, a first high-frequency signal including one or more harmonic components; and a second signal generating unit connected to an other end of the resonance circuit, and configured to generate, with the use of another switching system, a second high-frequency signal including a specific harmonic component, wherein the first high-frequency signal is adjusted in pulse width to a predetermined pulse width and input to the one end of the resonance circuit, and the second high-frequency signal is adjusted in pulse width to the predetermined pulse width and phase difference from the first high-frequency signal and input to the other end of the resonance circuit, wherein the predetermined pulse width is set to 1/n of a fundamental wave period T, where n represents a natural number, wherein the phase difference between the first high-frequency signal and the second high-frequency signal is set to ½ of the fundamental wave period T, and wherein the specific harmonic component included in the second high-frequency signal is substantially equal to at least one of the harmonic components included in the first high-frequency signal.
