Title:
POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/129451
Kind Code:
A1
Abstract:
A power transmission system for transmitting electrical energy from a transmission antenna (140) to a reception antenna (210) via an electromagnetic field, the power transmission system comprising: an inverter (130) for converting DC voltage into AC voltage having a prescribed frequency and outputting the AC voltage; a transmission-side control unit (150) for controlling the drive frequency of the inverter (130) and the voltage of the inputted DC voltage, and controlling so as to keep the power value outputted from the inverter (130) constant; a transmission antenna (140) into which the inverter (130) inputs the AC voltage; a rectifier (220) for rectifying the output from a reception antenna (210) into DC voltage; a step-up/step-down unit (230) for stepping up or stepping down and then outputting the DC voltage outputted by the rectifier (220); a battery charged by the output from the step-up/step-down unit (230); and a reception-side control unit (250) for controlling the step-up/step-down unit (230) and controlling so as to charge the battery using a maximum power value.
