Description
図1は、第1の実施形態に係る非接触給電システムの、給電装置と受電装置を含む構成を示すブロック図である。図1に示すように、非接触給電システムとしては、電力を給電する非接触給電装置10と、給電された電力を受電する受電装置20とを備えている。非接触給電装置10は送電回路11と送電コイル12を備え、受電装置20は受電コイル21を有している。非接触給電装置10から出力された電力は、送電コイル12と受電コイル21との間の電磁誘導または磁界共鳴等の電磁結合を利用して、受電装置20に給電される。
f60=1/2π√LC=20.37MHz≒20.34MHz
第2の実施形態では、一つの高調波ノイズを低減するだけでなく、複数の高調波の低減が可能な非接触給電装置について説明する。
f90=1/2π√LC=34.26MHz≒33.9MHz
