POWER TRANSMISSION EQUIPMENT AND NON-CONTACT POWER TRANSMISSION DEVICE

This power transmission equipment includes an AC power supply that outputs AC power, and a power transmitter to which said AC power is input. The power transmission equipment also includes an impedance converter that converts the input impedance of the power transmitter. The impedance converter is disposed between the AC power supply and the power transmitter. The constant of the impedance converter is set on the basis of the upper and lower limit values of the coupling coefficient.
