Abstract:
(EN) A system for transmitting an electric power from an electric power transmitting apparatus (10) to an electric power receiving apparatus (50) by use of the electromagnetic induction between a power receiving coil (60) and a power transmitting coil (40).  The electric power transmitting apparatus (10) comprises a power switching circuit (14), a first capacitor (20) and a power deriving circuit (30).  The power switching circuit (14), which includes a switching element (16) and an output point (P), switches the switching element (16) at a predetermined switching frequency (f), thereby causing the potential at the output point (P) to exhibit a predetermined variation, which is like a potential variation obtained by the half-wave rectification of a sinusoidal wave variation having a given amplitude.  The first capacitor (20) is connected between the output point (P) and a first fixed potential point (ground).  The power deriving circuit (30), which includes the power transmitting coil (40), causes an AC variation included in the foregoing predetermined variation to appear across the power transmitting coil (40).  The power deriving circuit (30) is connected between the output point (P) and a second fixed potential point (ground).
(FR) L'invention concerne un système de transfert d'énergie électrique d'un appareil émetteur d'énergie électrique (10) à un appareil récepteur d'énergie électrique (50) grâce à l'induction électromagnétique entre une bobine réceptrice d'énergie (60) et une bobine émettrice d'énergie (40). L'appareil émetteur d'énergie électrique (10) comprend un circuit commutateur d'énergie (14), un premier condensateur (20) et un circuit de production d'énergie (30). Le circuit de commutation d'énergie (14), qui comprend un élément de commutation (16) et un point de sortie (P), commute l'élément de commutation (16) à une fréquence de commutation prédéfinie (f), de façon à ce que le potentiel au point de sortie (P) présente une variation prédéfinie, analogue à une variation de potentiel obtenue par redressement d'une alternance d'une variation d'onde sinusoïdale présentant une amplitude donnée. Le premier condensateur (20) est monté entre le point de sortie (P) et un premier point à potentiel fixe (masse). Le circuit de production d'énergie (30), qui comprend la bobine émettrice d'énergie (40), fait apparaître aux bornes de la bobine émettrice d'énergie (40) une variation de courant alternatif contenue dans la variation prédéfinie susmentionnée. Le circuit de production d'énergie (30) est monté entre le point de sortie (P) et un deuxième point à potentiel fixe (masse).
(JA) 受電コイル60と送電コイル40との間の電磁誘導を利用して電力送信装置10から電力受信装置50に対して電力を送信するシステム。電力送信装置10は、電力スイッチング回路14と、第1キャパシタ20と、電力取出し回路30とを備えている。電力スイッチング回路14は、スイッチング素子16と出力点Pとを有しており、スイッチング素子16を所定スイッチング周波数fでスイッチすることにより出力点Pにおける電位を所定変動させる。ここで、所定変動は所定の振幅を有する正弦波変動を半波整流して得られるような電位変動である。第1キャパシタ20は、出力点Pと第1固定電位(グランド)との間に接続されている。電力取出し回路30は、送電コイル40を含んでおり、所定変動に含まれる交流的変化を送電コイル40の両端に生じさせるように構成されている。この電力取出し回路30は、出力点Pと第2固定電位(グランド)との間に接続されている。
