Abstract
An electric power transmission system for curbing reduction in power transmission transmits energy via an electromagnetic field from a power transmission antenna to a power receiving antenna including: an inverter converting DC to AC voltage of a predetermined frequency to output; a power transmission-side control unit controls a drive frequency of the inverter and DC voltage input to the inverter; controlling a power value output from the inverter kept at constant level; the power transmission antenna to which AC voltage is input from the inverter; a rectifying unit rectifies output of the power receiving antenna obtaining DC voltage, and outputs DC voltage; a step-up and step-down unit steps up or down DC voltage output from the rectifying to output; a battery is charged with output of step-up and step-down unit; and a power receiving-side control unit controls the step-up and step-down unit to charge the battery with maximum power value.
