Abstract
A power transmission system for transmitting electrical energy from a transmission antenna to a reception antenna via an electromagnetic field, including: an inverter for converting DC voltage into AC voltage having a prescribed frequency and outputting the AC voltage; a transmission-side control unit for performing a control for keeping the drive frequency of the inverter at a prescribed frequency, controlling the voltage of the DC voltage inputted into the inverter, and controlling to keep the power value outputted from the inverter constant; a transmission antenna into which the inverter inputs the AC voltage; a rectifier for rectifying the output from the reception antenna into DC voltage; a step-up/step-down unit for stepping up or down and then outputting the DC voltage from the rectifier; a battery charged by the output from the step-up/step-down unit; and a reception-side control unit for controlling the step-up/step-down unit and charging the battery most efficiently.
