Description

本発明は、物理的に接続することなく電力を伝送する送電装置、及び該送電装置を用いる電力伝送システムに関する。   The present invention relates to a power transmission device that transmits power without being physically connected, and a power transmission system that uses the power transmission device.

近年、非接触で電力を伝送する電子機器が多々開発されている。電子機器において非接触で電力を伝送するためには、電力の送電ユニットと、電力の受電ユニットとの双方にコイルモジュールを設けた磁界結合方式の電力伝送システムが採用されることが多い。   In recent years, many electronic devices that transmit power without contact have been developed. In order to transmit electric power in an electronic device in a non-contact manner, a magnetic field coupling type electric power transmission system in which coil modules are provided in both the electric power transmission unit and the electric power reception unit is often employed.

しかし、磁界結合方式では、各コイルモジュールを通過する磁束の大きさが起電力に大きく影響され、電力を高い効率で伝送するためには、送電ユニット側（一次側）のコイルモジュールと受電ユニット側（二次側）のコイルモジュールとのコイル平面方向の相対位置の制御に高い精度が要求される。また、結合電極としてコイルモジュールを用いているので、送電ユニット及び受電ユニットの小型化が難しくなる。さらに、携帯機器等では、コイルの発熱による蓄電池への影響を考慮する必要があり、配置設計上のボトルネックになるおそれがあるという問題もあった。   However, in the magnetic field coupling method, the magnitude of the magnetic flux passing through each coil module is greatly affected by the electromotive force, and in order to transmit power with high efficiency, the coil module on the power transmission unit side (primary side) and the power reception unit side High accuracy is required for controlling the relative position in the coil plane direction with the coil module on the (secondary side). In addition, since the coil module is used as the coupling electrode, it is difficult to reduce the size of the power transmission unit and the power reception unit. Further, in portable devices and the like, it is necessary to consider the influence on the storage battery due to the heat generated by the coil, and there is also a problem that it may become a bottleneck in layout design.

そこで、例えば静電界を用いた電力の伝送システムが開示されている。特許文献１では、送電ユニットの結合電極から受電ユニットの結合電極に静電界を介して電力が伝送される伝送システムが開示されている。特許文献１では、静電界を用いているので、結合電極の平面方向の相対位置を高い精度で制御する必要がなく、結合電極の形状設計の自由度が高い。   Thus, for example, a power transmission system using an electrostatic field is disclosed. Patent Document 1 discloses a transmission system in which electric power is transmitted from a coupling electrode of a power transmission unit to a coupling electrode of a power receiving unit via an electrostatic field. In Patent Document 1, since an electrostatic field is used, it is not necessary to control the relative position of the coupling electrode in the planar direction with high accuracy, and the degree of freedom in designing the shape of the coupling electrode is high.

また、特許文献２では、送電ユニット側の結合電極と、受電ユニット側の結合電極との間に強い電場を形成することにより高い電力伝送効率を具現化したエネルギー搬送装置が開示されている。特許文献２では、送電ユニット側に大きいサイズの受動電極と小さいサイズの能動電極とを備え、受電ユニット側にも大きいサイズの受動電極と小さいサイズの能動電極とを備えている。送電ユニット側の能動電極と受電ユニット側の能動電極との間に強い電場を形成することにより、高い電力伝送効率を実現している。   Patent Document 2 discloses an energy transfer device that realizes high power transmission efficiency by forming a strong electric field between the coupling electrode on the power transmission unit side and the coupling electrode on the power reception unit side. In Patent Document 2, a large size passive electrode and a small size active electrode are provided on the power transmission unit side, and a large size passive electrode and a small size active electrode are also provided on the power receiving unit side. High electric power transmission efficiency is realized by forming a strong electric field between the active electrode on the power transmission unit side and the active electrode on the power reception unit side.

Yes. That is, the active electrode (second active electrode) 11a, the passive electrode (second passive electrode) 11p, the active electrode (first active electrode) 21a, and the passive electrode (first passive electrode) 21p are asymmetrical.

And the passive electrode (first passive electrode) 21p form a capacitance, respectively, and by disposing in a strong electric field, it is possible to transmit power by capacitive coupling. The transmitted power is stepped down by the step-down transformer 23 and supplied to the load circuit 22. In FIG. 2, the resonance circuit is also included, but this is for enhancing the stability of power transmission, and the resonance circuit is not necessarily required.

図３は、本発明の実施の形態に係る電力伝送システムの構成を模式的に示す機能ブロック図である。図３に示すように、送電装置１の交流電源１０１から供給される交流電力は増幅器１０２で増幅され、昇圧トランス１０３で昇圧されて結合電極１０４へ供給される。結合電極１０４は後述する支持板に配置され、交流電源１０１、増幅器１０２、昇圧トランス１０３は後述する送電台に内蔵される。送電装置１の結合電極１０４から受電装置２の結合電極２０１へ伝送された電力は降圧トランス２０２により降圧され、整流部２０３で整流されたのち、負荷２０４へ供給される。   FIG. 3 is a functional block diagram schematically showing the configuration of the power transmission system according to the embodiment of the present invention. As shown in FIG. 3, AC power supplied from the AC power supply 101 of the power transmission device 1 is amplified by the amplifier 102, boosted by the boost transformer 103, and supplied to the coupling electrode 104. The coupling electrode 104 is disposed on a support plate described later, and the AC power source 101, the amplifier 102, and the step-up transformer 103 are built in a power transmission stand described later. The power transmitted from the coupling electrode 104 of the power transmission device 1 to the coupling electrode 201 of the power reception device 2 is stepped down by the step-down transformer 202, rectified by the rectification unit 203, and then supplied to the load 204.

ここで、送電装置１の結合電極１１（能動電極１１ａ、受動電極１１ｐ）及び受電装置２の結合電極２１（能動電極２１ａ、受動電極２１ｐ）は、それぞれ導電性を有する材料にて形成される。例えば銅、金、銀等の導体、これらの化合物を用いることができる。導電性を有する材料にて形成された結合電極１１と結合電極２１とを、互いに静電結合が生じる位置に配置することにより、結合電極１１と結合電極２１との間に静電容量が生じる。生じる静電容量の大きさに応じて電力伝送効率が変動する。   Here, the coupling electrode 11 (active electrode 11a, passive electrode 11p) of the power transmission device 1 and the coupling electrode 21 (active electrode 21a, passive electrode 21p) of the power receiving device 2 are each formed of a conductive material. For example, conductors such as copper, gold, and silver, and these compounds can be used. Capacitance is generated between the coupling electrode 11 and the coupling electrode 21 by arranging the coupling electrode 11 and the coupling electrode 21 formed of a conductive material at a position where electrostatic coupling occurs with each other. The power transmission efficiency varies depending on the size of the generated capacitance.

図４は、本発明の実施の形態に係る電力伝送システムの送電装置１の構成を模式的に示す斜視図である。図４の例では、送電装置１の本体部分を構成する送電台４０の一面に、能動電極（第二の能動電極）１１ａと受動電極（第二の受動電極）１１ｐとを配置してある支持板４１を装着する。   FIG. 4 is a perspective view schematically showing the configuration of the power transmission device 1 of the power transmission system according to the embodiment of the present invention. In the example of FIG. 4, a support in which an active electrode (second active electrode) 11 a and a passive electrode (second passive electrode) 11 p are arranged on one surface of a power transmission stand 40 constituting the main body portion of the power transmission device 1. A plate 41 is attached.

支持板４１には、能動電極１１ａと受動電極１１ｐとが所定の大きさで、所定の間隔を隔てて配置してある。能動電極１１ａ及び受動電極１１ｐの大きさ、及び両電極の配置間隔は、当該支持板４１を用いて電力を伝送する受電装置２の能動電極（第一の能動電極）２１ａ及び受動電極（第一の受動電極）２１ｐの大きさ、及び両電極の配置間隔に合わせてある。したがって、受電装置２ごとに対応する支持板４１を複数準備しておく。   On the support plate 41, the active electrode 11a and the passive electrode 11p have a predetermined size and are arranged at a predetermined interval. The size of the active electrode 11a and the passive electrode 11p, and the arrangement interval between the two electrodes are the active electrode (first active electrode) 21a and the passive electrode (first electrode) of the power receiving device 2 that transmits power using the support plate 41. The passive electrode) 21p, and the arrangement interval of both electrodes. Therefore, a plurality of support plates 41 corresponding to each power receiving device 2 are prepared.

支持板４１は、シート状のフレキシブルな材質で形成されていても良いし、板状のリジッドな材質で形成されていても良い。また、単層構造であっても良いし、多層構造であっても良い。さらに、支持板４１が多層構造である場合、電極の保護、安全性等の観点から、能動電極１１ａ及び受動電極１１ｐは支持板４１の内層に設けてあることが好ましい。   The support plate 41 may be formed of a sheet-like flexible material, or may be formed of a plate-like rigid material. Moreover, a single layer structure may be sufficient and a multilayer structure may be sufficient. Furthermore, when the support plate 41 has a multilayer structure, the active electrode 11a and the passive electrode 11p are preferably provided in the inner layer of the support plate 41 from the viewpoints of electrode protection, safety, and the like.

支持板４１の能動電極１１ａ及び受動電極１１ｐは、それぞれ所定の位置、好ましくは支持板４１の四隅のうちの２か所に設けてある第一の端子４１１、第二の端子４１２と、導体（銅メッキ等）により、それぞれ電気的に接続してある。そして、送電台４０の表面には、第一の端子４１１、第二の端子４１２と対応する位置に、それぞれ第三の端子４０１、第四の端子４０２を設けてある。支持板４１の四隅のうちの残り２か所に対応する位置には、送電台４０と支持板４１とを固定するための固定部材４０３が設けてある。なお、第三の端子４０１、第四の端子４０２は、それぞれ交流電源に接続してある。   The active electrode 11a and the passive electrode 11p of the support plate 41 are respectively provided with a first terminal 411 and a second terminal 412 provided at predetermined positions, preferably at two of the four corners of the support plate 41, and conductors ( Each is electrically connected by copper plating or the like. And on the surface of the power transmission stand 40, the 3rd terminal 401 and the 4th terminal 402 are provided in the position corresponding to the 1st terminal 411 and the 2nd terminal 412, respectively. Fixing members 403 for fixing the power transmission stand 40 and the support plate 41 are provided at positions corresponding to the remaining two of the four corners of the support plate 41. The third terminal 401 and the fourth terminal 402 are each connected to an AC power source.

第一の端子４１１、第二の端子４１２と、第三の端子４０１、第四の端子４０２との接続には、例えば板バネ構造の端子を設けて圧接させるコネクタを用いても良い。もちろん、電気接点を介して接続する方法に限定されるものではなく、例えば容量を介して接続する方法であっても良い。   For the connection between the first terminal 411 and the second terminal 412, and the third terminal 401 and the fourth terminal 402, for example, a connector having a leaf spring structure may be used. Of course, it is not limited to the method of connecting via an electrical contact, and for example, a method of connecting via a capacitor may be used.

支持板４１の能動電極１１ａ及び受動電極１１ｐの位置は、対応する受電装置２の能動電極２１ａ及び受動電極２１ｐの位置に応じて変動するが、第一の端子４１１、第二の端子４１２の位置は一定（同じ）にする。このようにすることで、受電装置２の形状、サイズ等が相違する場合であっても、支持板４１の第一の端子４１１、第二の端子４１２と、送電台４０の第三の端子４０１、第四の端子４０２とは、電気的に確実に接続される。   The positions of the active electrode 11a and the passive electrode 11p of the support plate 41 vary depending on the positions of the active electrode 21a and the passive electrode 21p of the corresponding power receiving device 2, but the positions of the first terminal 411 and the second terminal 412 Is constant (same). By doing in this way, even if the shape, size, etc. of the power receiving apparatus 2 are different, the first terminal 411 and the second terminal 412 of the support plate 41 and the third terminal 401 of the power transmission stand 40 are used. The fourth terminal 402 is electrically and reliably connected.

図５は、本発明の実施の形態に係る電力伝送システムの電力伝送時の一例を示す斜視図である。例えば図５に示すように、受電装置２の能動電極２１ａ及び受動電極２１ｐの位置に対応して能動電極１１ａ及び受動電極１１ｐを配置してある支持板４１を、送電台４０の上に装着し、その上に受電装置２を載置する。ここで、受電装置２は、例えば移動体通信端末、デジタルカメラ等の電子機器である。   FIG. 5 is a perspective view showing an example during power transmission of the power transmission system according to the embodiment of the present invention. For example, as shown in FIG. 5, a support plate 41 on which the active electrode 11 a and the passive electrode 11 p are arranged corresponding to the positions of the active electrode 21 a and the passive electrode 21 p of the power receiving device 2 is mounted on the power transmission stand 40. Then, the power receiving device 2 is placed thereon. Here, the power receiving apparatus 2 is an electronic device such as a mobile communication terminal or a digital camera.

図６及び図７は、本発明の実施の形態に係る電力伝送システムの受電装置２の相違に基づく支持板４１の構成を模式的に示す例示図である。まず図６（ｂ）に示すように、支持板４１の表面には、図６（ａ）に示す受電装置２が載置されるべき位置を示す位置決めマーク６１が設けてある。なお、受電装置２が載置される位置が多少ずれても問題が生じない程度に、受電装置２の第一の結合電極（第一の能動電極２１ａ及び第一の受動電極２１ｐ）の配置面積より送電装置１の第二の結合電極（第二の能動電極１１ａ及び第二の受動電極１１ｐ）の配置面積の方が大きいことが好ましい。   6 and 7 are exemplary views schematically showing the configuration of the support plate 41 based on the difference of the power receiving device 2 of the power transmission system according to the embodiment of the present invention. First, as shown in FIG. 6B, a positioning mark 61 indicating the position where the power receiving device 2 shown in FIG. 6A is to be placed is provided on the surface of the support plate 41. The arrangement area of the first coupling electrodes (the first active electrode 21a and the first passive electrode 21p) of the power receiving device 2 is such that no problem occurs even if the position where the power receiving device 2 is placed is slightly shifted. It is preferable that the arrangement area of the second coupling electrodes (second active electrode 11a and second passive electrode 11p) of the power transmission device 1 is larger.

図６の例では受電装置２が載置された場合の四隅の位置を位置決めマーク６１で示しているが、特にこれに限定されるものではない。すなわち、四辺の位置を示すものであっても良いし、平面的なマーク（印）に限定せず、受電装置２の一辺又は一角を当接させて位置決めするような構造物であっても良い。   In the example of FIG. 6, the positions of the four corners when the power receiving device 2 is placed are indicated by the positioning marks 61, but are not particularly limited thereto. That is, it may indicate the positions of the four sides, and is not limited to a planar mark (mark), and may be a structure that is positioned by contacting one side or one corner of the power receiving device 2. .

図７（ａ）に示すように、図６（ａ）に示す受電装置２よりもサイズが小さく、結合電極の個数、配置されている位置が相違する受電装置２に対して電力を伝送する場合、図６（ｂ）に示した支持板４１を図７（ｂ）に示す支持板４１ｂに交換する。図６（ｂ）に示す支持板４１にて第一の端子４１１及び第二の端子４１２が配置されている位置は、図７（ｂ）に示す支持板４１ｂにて第一の端子４１１及び第二の端子４１２が配置されている位置と同じである。すなわち、交換することが可能な全ての支持板において、第一の端子４１１及び第二の端子４１２が配置されている位置が共通化されている。   As shown in FIG. 7A, when power is transmitted to the power receiving device 2 that is smaller in size than the power receiving device 2 shown in FIG. 6A and has a different number of coupling electrodes and different positions. The support plate 41 shown in FIG. 6B is replaced with a support plate 41b shown in FIG. The positions where the first terminal 411 and the second terminal 412 are arranged on the support plate 41 shown in FIG. 6B are the same as the positions of the first terminal 411 and the second terminal on the support plate 41b shown in FIG. The position is the same as the position where the second terminal 412 is disposed. That is, the position where the first terminal 411 and the second terminal 412 are arranged is common in all the support plates that can be exchanged.

以上のように本実施の形態によれば、送電装置１の支持板４１は、電力を伝送する受電装置２に応じて交換することが可能であることから、受電装置２の形状、サイズ等が相違する場合であっても、あるいは受電装置２側の能動電極２１ａ及び／又は受動電極２１ｐの大きさ、個数、配置されている位置等が相違している場合であっても、対応する位置に能動電極１１ａ及び／又は受動電極１１ｐを配置してある支持板４１に交換することで、様々な電子機器、機種について効率良く電力を伝送することが可能となる。   As described above, according to the present embodiment, the support plate 41 of the power transmission device 1 can be replaced according to the power reception device 2 that transmits power. Even if they are different, or even if the size, number, position, etc. of the active electrode 21a and / or the passive electrode 21p on the power receiving device 2 side are different, they are in the corresponding positions. By replacing the active plate 11a and / or the passive electrode 11p with the support plate 41 on which the active electrode 11a and / or the passive electrode 11p are arranged, it is possible to efficiently transmit power for various electronic devices and models.

なお、上述した実施の形態では、支持板４１に能動電極１１ａ及び受動電極１１ｐの両方を配置してある例について説明しているが、特にこれに限定されるものではなく、例えば能動電極１１ａを支持板４１に設け、送電台４０に受動電極１１ｐを設けるというように、支持板４１には、能動電極１１ａ又は受動電極１１ｐのいずれか一方のみが設けられていても良い。あるいは、能動電極１１ａ専用の支持板４１と、受動電極１１ｐ専用の支持板４１とを別個に設けておき、それぞれの支持板４１をそれぞれ交換することが可能としておいても良い。   In the above-described embodiment, an example in which both the active electrode 11a and the passive electrode 11p are arranged on the support plate 41 has been described. However, the present invention is not particularly limited thereto. Only one of the active electrode 11a or the passive electrode 11p may be provided on the support plate 41, such as providing the support plate 41 and providing the passive electrode 11p on the power transmission stand 40. Alternatively, the support plate 41 dedicated to the active electrode 11a and the support plate 41 dedicated to the passive electrode 11p may be provided separately so that each support plate 41 can be replaced.

また、送電装置１を立てて、又は傾斜させて使用することを想定して、送電台４０の能動電極１１ａ及び受動電極１１ｐの中心を結ぶ方向のいずれか一端に、受電装置２の位置決め機構を備えても良い。図８は、本発明の実施の形態に係る電力伝送システムの送電装置１に受電装置２を載置した状態を示す模式図である。図８の例では、図面の縦方向が上下方向を示しており、送電装置１を立てて使用している状態を示している。   Further, assuming that the power transmission device 1 is used upright or inclined, a positioning mechanism of the power reception device 2 is provided at one end in a direction connecting the centers of the active electrode 11a and the passive electrode 11p of the power transmission table 40. You may prepare.

In the example of FIG. 8, the vertical direction of the drawing indicates the vertical direction, and shows a state where the power transmission device 1 is used upright.

図８（ａ）の平面図及び図８（ｂ）の左側面図に示すように、送電装置１は、能動電極１１ａ及び受動電極１１ｐが設けてある支持板４１よりも前方へ突出している、支持板４１及び受電装置２を支持する支持部８１を備えている。受電装置２を送電装置１に載置する場合、受電装置２の一端が支持部８１に接触するまでスライドさせ、接触した状態で送電装置１の能動電極１１ａ及び受動電極１１ｐ、受電装置２の能動電極２１ａ及び受動電極２１ｐの位置合わせができるようになっている。支持板４１及び受電装置２を支持する支持部８１を、送電台４０の能動電極１１ａ及び受動電極１１ｐの中心を結ぶ方向のいずれか一端に設けておき、送電装置１を立てて使用する場合には支持部８１が下方になるようにして使用する。   As shown in the plan view of FIG. 8A and the left side view of FIG. 8B, the power transmission device 1 projects forward from the support plate 41 on which the active electrode 11a and the passive electrode 11p are provided. A support portion 81 that supports the support plate 41 and the power receiving device 2 is provided. When the power receiving device 2 is placed on the power transmitting device 1, the power receiving device 2 is slid until one end of the power receiving device 2 comes into contact with the support portion 81, and the active electrode 11 a and the passive electrode 11 p of the power transmitting device 1 are The electrode 21a and the passive electrode 21p can be aligned. When the support portion 41 that supports the support plate 41 and the power receiving device 2 is provided at one end in the direction connecting the centers of the active electrode 11a and the passive electrode 11p of the power transmission stand 40, and the power transmission device 1 is used upright. Is used with the support part 81 positioned downward.

なお、送電台４０に、第二の能動電極１１ａ及び第二の受動電極１１ｐの中心を結ぶ方向の溝部を、第二の能動電極１１ａ及び第二の受動電極１１ｐの中心を結ぶ方向と直交する方向の両端部に設けておき、第三の端子４０１及び第四の端子４０２を溝部に設けておいても良い。図９は、本発明の実施の形態に係る電力伝送システムの送電装置１の溝部を模式的に示す斜視図である。   In addition, the groove part in the direction connecting the centers of the second active electrode 11a and the second passive electrode 11p to the power transmission stand 40 is orthogonal to the direction connecting the centers of the second active electrode 11a and the second passive electrode 11p. The third terminal 401 and the fourth terminal 402 may be provided in the groove portion at both ends in the direction. FIG. 9 is a perspective view schematically showing a groove portion of power transmission device 1 of the power transmission system according to the embodiment of the present invention.

図９（ｂ）に示すように送電台４０には、支持板４１を抜き差しすることが可能な溝部９１を設けておく。支持板４１を図面の上方から下方に向かってスライドさせながら差し込む。溝部９１に第三の端子４０１、第四の端子４０２を設けておき、支持板４１の差し込む方向と直交する方向の両端に第一の端子４１１、第二の端子４１２を設けておく。   As shown in FIG. 9B, the power transmission stand 40 is provided with a groove portion 91 into which the support plate 41 can be inserted and removed. The support plate 41 is inserted while sliding downward from above in the drawing. A third terminal 401 and a fourth terminal 402 are provided in the groove portion 91, and a first terminal 411 and a second terminal 412 are provided at both ends in a direction orthogonal to the direction in which the support plate 41 is inserted.

このようにすることで、支持板４１は、溝部９１に沿ってスライドさせることにより容易に送電台４０に装着することができる。しかも、支持板４１を溝部９１に沿って差し込んだ場合に、第一の端子４１１及び第二の端子４１２と、第三の端子４０１及び第四の端子４０２とが、それぞれ電気的に接続することでき、支持板４１を交換した場合であっても、第一の端子４１１及び第二の端子４１２に確実に通電することができ、一の送電台４０にて複数の支持板４１を差し替えて装着することが可能となる。なお、図９（ａ）では支持板４１の両端のいずれか一辺上のみに第一の端子４１１、第二の端子４１２を設けているが、図９（ｃ）に示すように支持板４１の両端の辺上にそれぞれ第一の端子４１１と第二の端子４１２とを分散して設けても良い。   By doing so, the support plate 41 can be easily attached to the power transmission stand 40 by sliding along the groove 91. Moreover, when the support plate 41 is inserted along the groove portion 91, the first terminal 411 and the second terminal 412 are electrically connected to the third terminal 401 and the fourth terminal 402, respectively. Even when the support plate 41 is replaced, the first terminal 411 and the second terminal 412 can be reliably energized, and the plurality of support plates 41 are replaced and mounted in one power transmission stand 40. It becomes possible to do. In FIG. 9A, the first terminal 411 and the second terminal 412 are provided only on one side of both ends of the support plate 41. However, as shown in FIG. The first terminal 411 and the second terminal 412 may be provided in a distributed manner on both sides.

なお、送電装置１の能動電極と受電装置２の能動電極とを対向させるように、送電装置１の受動電極、能動電極、受電装置２の能動電極、受動電極の順に結合電極を配置してあっても良い。図１０は、本発明の実施の形態に係る電力伝送システムの送電装置１に受電装置２を載置した状態を示す模式図である。図１０に示すように、送電装置１は、能動電極１１ａを受電装置２側へ、受動電極１１ｐを受電装置２と反対側へ、それぞれ配置してある。一方、受電装置２も、能動電極２１ａを送電装置１側へ、受動電極２１ｐを送電装置２と反対側へ、それぞれ配置してある。   The coupling electrode is arranged in the order of the passive electrode of the power transmission device 1, the active electrode, the active electrode of the power reception device 2, and the passive electrode so that the active electrode of the power transmission device 1 and the active electrode of the power reception device 2 are opposed to each other. May be. FIG. 10 is a schematic diagram illustrating a state where the power receiving device 2 is placed on the power transmitting device 1 of the power transmission system according to the embodiment of the present invention. As shown in FIG. 10, in the power transmission device 1, the active electrode 11 a is disposed on the power reception device 2 side, and the passive electrode 11 p is disposed on the opposite side to the power reception device 2. On the other hand, the power receiving device 2 is also arranged with the active electrode 21a on the power transmission device 1 side and the passive electrode 21p on the opposite side to the power transmission device 2, respectively.

送電装置１の能動電極１１ａは、交換することが可能な支持板４１に設けてある。したがって、受電装置２の能動電極２１ａの大きさに応じて、対応する大きさの能動電極１１ａが設けてある支持板４１に差し替えることにより、高い効率で電力を伝送することができる。   The active electrode 11a of the power transmission device 1 is provided on a support plate 41 that can be replaced. Therefore, according to the size of the active electrode 21a of the power receiving device 2, the power can be transmitted with high efficiency by replacing the support plate 41 provided with the corresponding active electrode 11a.

また、受電装置２の能動電極２１ａよりも、受電装置２の受動電極２１ｐの方が大きいことが好ましい。送電装置１の能動電極１１ａ及び受電装置２の能動電極２１ａを近接させることにより、両電極間に強い電場を形成するためには、送電装置１の受動電極１１ｐと受電装置２の受動電極２１ｐとの間に生じる容量をなるべく大きくすることが好ましいからである。   The passive electrode 21p of the power receiving device 2 is preferably larger than the active electrode 21a of the power receiving device 2. In order to form a strong electric field between both electrodes by bringing the active electrode 11a of the power transmission device 1 and the active electrode 21a of the power reception device 2 close to each other, the passive electrode 11p of the power transmission device 1 and the passive electrode 21p of the power reception device 2 This is because it is preferable to increase the capacity generated during the period as much as possible.

以上のように本実施の形態によれば、受電装置２の送電装置１における縦方向の位置を固定することができ、ユーザが意識することなく電力を高い効率で伝送することが可能な相対位置に受電装置２を載置することが可能となる。   As described above, according to the present embodiment, the vertical position in the power transmission device 1 of the power receiving device 2 can be fixed, and the relative position at which power can be transmitted with high efficiency without being conscious of the user. It becomes possible to mount the power receiving apparatus 2 on the mobile phone.

その他、本発明は上記実施例に限定されるものではなく、本発明の趣旨の範囲内であれば多種の変形、置換等が可能であることは言うまでもない。例えば、送電装置１の能動電極１１ａ及び受動電極１１ｐは、非対称形状である必要はなく、同一のサイズ、同一の形状であっても良い。同様に、受電装置２の能動電極２１ａ及び受動電極２１ｐも、非対称形状である必要はなく、同一のサイズ、同一の形状であっても良い。   In addition, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications and substitutions are possible within the scope of the gist of the present invention. For example, the active electrode 11a and the passive electrode 11p of the power transmission device 1 do not have to be asymmetrical shapes, and may have the same size and the same shape. Similarly, the active electrode 21a and the passive electrode 21p of the power receiving device 2 do not need to be asymmetrical, and may have the same size and the same shape.
