PROBLEM TO BE SOLVED: To provide a power transmission apparatus and non-contact power transmission device having the same, capable of eliminating each noise generated by switching each switching element with a simple configuration.SOLUTION: A non-contact power transmission device 10 includes a ground apparatus 11 installed on the ground and a vehicle apparatus 21 installed on a vehicle. On the ground apparatus 11, a high-frequency power supply 12 for outputting high-frequency power is installed. The high-frequency power supply 12 includes an AC-DC converter 12a with a switching element 12aa for AC-DC switching periodically and a DC-RF converter 12b with a switching element 12bb for DC-RF switching periodically. Meanwhile, a switching frequency of each of the switching elements 12aa, 12bb is set at the same. |
