PROBLEM TO BE SOLVED: To provide a power transmission system capable of performing efficient power transmission on the basis of an amount of positional deviation between a power transmission antenna and a power reception antenna, while setting a parameter of a step-up/step-down unit on the power reception system side with a simple configuration.SOLUTION: A power transmission system detects a frequency of AC voltage input to a power reception antenna 210; and adjusts current and voltage input to a step-up/step-down unit 230 depending on the detected frequency. Thereby, a parameter of the step-up/step-down unit 230 on the power reception system side can be set with a simple configuration; and efficient power transmission based on an amount of positional deviation between the power transmission antenna 140 and the power reception antenna 210 can be performed. |
