<p>A power transmission system a power transmission apparatus, a center frequency acquiring unit, and a control unit. The power transmission apparatus includes a primary-side coupling electrode electrically configured to couple to a secondary-side coupling electrode and connected load circuit of a power receiving apparatus, a high-frequency voltage generating circuit configured to generate and apply a high-frequency voltage to the primary-side coupling electrode, and a driving power circuit that supplies driving power to the high-frequency voltage generating circuit. The center frequency acquiring unit acquires a center frequency at which a high-frequency high voltage applied to coupling electrode is minimized in a state in which a low load is applied to the secondary-side coupling electrode of the power receiving apparatus and the frequency of the generated high-frequency voltage is varied. The control unit sets a driving frequency of the high-frequency voltage generating circuit at or near the center frequency to supply power to the power receiving apparatus.</p> |
