POWER SUPPLY SYSTEM AND POWER SUPPLY METHOD

PROBLEM TO BE SOLVED: To provide a power supply system and power supply method for supplying stable power in a simple configuration using an electric supply line.SOLUTION: The power supply system includes: an electric supply line 1 formed into a loop shape, and contactlessly supplying power to a power reception device 200; and a progressive wave generator 2s having a plurality of high frequency power supplies 22a and 22b for generating a progressive wave for supplying power to the electric supply line. The positions of the plurality of high frequency power supplies 22a and 22b are determined such that the phases of high frequency waves outputted from the high frequency power supplies 22a and 22b synchronize with each other.SELECTED DRAWING: Figure 5 【課題】給電線を用い、簡易な構成で安定した電力を供給可能な給電システム及び給電方法を提供する。【解決手段】ループ状に形成され、受電装置２００に対して非接触で電力を供給する給電線１と、電力を供給するための進行波を給電線に発生させる複数の高周波電源２２ａ、２２ｂを有する進行波生成装置２ｓと、を備え、複数の高周波電源２２ａ、２２ｂの位置は、それぞれの高周波電源２２ａ、２２ｂから出力される高周波の位相が同期するように、定められている。【選択図】図５
