As shown in FIGS. 9 and 10, the power transmission devices 10B, 11B, 12B according to the third embodiment are provided by the power transmission unit 21 in addition to the configurations of the power transmission devices 10A, 11A, 12A according to the first embodiment. Further, a control unit 40 is further provided to control the power supplied to the power receiving unit 221 in a non-contact manner so as to be changeable. The control unit 40 is arranged on the side of the power transmission unit 21, and is electrically connected between the first device connecting unit 23 and the second device connecting unit 24. If the control unit 40 can changeably control the power supplied to the power receiving unit 221 in a non-contact manner by the power transmission unit 21 of each of the power transmission devices 10B, 11B, 12B, the control unit 40 is outside the power transmission devices 10B, 11B, 12B. It may be arranged in.
　制御部４０は、例えば、ＣＰＵ[Central Processing Unit]、ＲＯＭ[Read Only Memory]、ＲＡＭ[Random Access Memory]等を含む電子制御ユニットである。制御部４０は、上記の電源ユニット６０の制御部６１と同様に、電源６２から受電した単相交流電力又は三相交流電力を整流及び昇圧して直流電力に変換するＡＣ／ＤＣコンバータ及びＡＣ／ＤＣコンバータにより整流及び昇圧された直流電力を電源６２から受電した交流電力よりも周波数が高い交流電力に変換するＤＣ／ＡＣインバータを含む。 The control unit 40 is an electronic control unit including, for example, a CPU [Central Processing Unit], a ROM [Read Only Memory], a RAM [Random Access Memory], and the like. Similar to the control unit 61 of the power supply unit 60, the control unit 40 rectifies and boosts the single-phase AC power or three-phase AC power received from the power supply 62 and converts the AC / DC converter and AC / into DC power. It includes a DC / AC inverter that converts DC power rectified and boosted by a DC converter into AC power having a higher frequency than AC power received from the power supply 62.
　ＡＣ／ＤＣコンバータ及びＤＣ／ＡＣインバータのいずれか一方又は双方を制御することにより、例えば、ＡＣ／ＤＣコンバータ及びＤＣ／ＡＣインバータを構成するＩＧＢＴやＭＯＳＦＥＴなどの電力制御素子のスイッチングのデューティ比、タイミング又は周波数を変化させることにより、制御部４０は送電部２１により受電部２２１に非接触で供給する電力を変更可能に制御することができる。 By controlling one or both of the AC / DC converter and the DC / AC inverter, for example, the switching duty ratio and timing of switching power control elements such as IGBTs and MOSFETs constituting the AC / DC converter and the DC / AC inverter. Alternatively, by changing the frequency, the control unit 40 can changeably control the power supplied to the power receiving unit 221 by the power transmitting unit 21 in a non-contact manner.
　制御部４０において、第１装置連結部２３と第２装置連結部２４との間はたとえばバスバーにより電気的に直結され、ＡＣ／ＤＣコンバータがバスバーから電気的に分岐するように接続される。よって、制御部４０が受電した単相交流電力又は三相交流電力のうち、ＡＣ／ＤＣコンバータ及びＤＣ／ＡＣインバータによって周波数が高い交流電力に変換されない電力は、変換されずに、接続された他の制御部４０へ送電される。 In the control unit 40, the first device connecting unit 23 and the second device connecting unit 24 are electrically directly connected by, for example, a bus bar, and the AC / DC converter is connected so as to electrically branch from the bus bar. Therefore, of the single-phase AC power or three-phase AC power received by the control unit 40, the power that is not converted into high-frequency AC power by the AC / DC converter and DC / AC inverter is connected without being converted. It is transmitted to the control unit 40 of.
　本実施形態に係る道路床版１００Ａは、単数の本実施形態の送電装置１０Ｂ，１１Ｂ，１２Ｂを含む。図１０に示されるように、複数の道路床版１００Ａが互いに一列をなして連結されることにより、本実施形態の送電システム１０００Ｃが構成される。図１０中で、電源６２から受電し、変換されていない交流電力は破線で示される。また、図１０中で、変換された交流電力は実線で示される。 The road deck 100A according to the present embodiment includes a single power transmission device 10B, 11B, 12B of the present embodiment. As shown in FIG. 10, a plurality of road decks 100A are connected to each other in a line to form the power transmission system 1000C of the present embodiment. In FIG. 10, the AC power received from the power source 62 and not converted is shown by a broken line. Further, in FIG. 10, the converted AC power is shown by a solid line.
　図９及び図１０に示されるように、制御部４０は、外部からの制御信号を受信する無線アンテナ４１を有する。無線アンテナ４１により受信した制御信号に応じて、制御部４０は、送電部２１により受電部２２１に非接触で供給する電力を変更可能に制御する。また、制御部４０は、信号ライン２８により受信した制御信号に応じて、制御部４０は、送電部２１により受電部２２１に非接触で供給する電力を変更可能に制御してもよい。制御信号の受信を容易にするため、無線アンテナ４１の上部は無線電波を透過するプラスチック等の材料で覆われているか、又は無線アンテナ４１の一部若しくは全体が路面Ｓに露出していることが望ましい。 As shown in FIGS. 9 and 10, the control unit 40 has a radio antenna 41 that receives a control signal from the outside. In response to the control signal received by the wireless antenna 41, the control unit 40 controls the power transmission unit 21 so as to be able to change the power supplied to the power reception unit 221 in a non-contact manner. Further, the control unit 40 may be able to change the power supplied to the power receiving unit 221 by the power transmission unit 21 in a non-contact manner according to the control signal received by the signal line 28. In order to facilitate reception of the control signal, the upper part of the wireless antenna 41 may be covered with a material such as plastic that transmits radio waves, or a part or the whole of the wireless antenna 41 may be exposed on the road surface S. desirable.
　図１０に示されるように、送電装置１０Ｂの制御部４０は、送電部２１により受電部２２１に非接触で供給する電力を０とし、第１の他の送電装置１１Ｂから受電した電力の全てを第２の他の送電装置１２Ｂに送電することも可能である。この場合、送電装置１０Ｂは、他の送電装置１１Ｂと送電装置１２Ｂとの間の電路として機能する。図１０の例では、送電装置１１Ｂの制御部４０は、電源６２から受電した電力を変換し、送電装置１１Ｂの送電部２１に供給する。変換された電力により送電装置１１Ｂの送電部２１は、車両２００に搭載された受電装置２２０の受電部２２１に非接触で電力を供給する。また、送電装置１１Ｂの制御部４０は、電源６２から受電した電力を変換せずに送電装置１０Ｂに送電する。送電装置１０Ｂに送電される電力は、電源６２から受電した電力から、送電装置１１Ｂの送電部２１に供給された電力の分だけ減っている。 As shown in FIG. 10, the control unit 40 of the power transmission device 10B sets the power supplied to the power reception unit 221 by the power transmission unit 21 in a non-contact manner to 0, and receives all the power received from the first other power transmission device 11B. It is also possible to transmit power to the second other power transmission device 12B. In this case, the power transmission device 10B functions as an electric line between the other power transmission device 11B and the power transmission device 12B. In the example of FIG. 10, the control unit 40 of the power transmission device 11B converts the electric power received from the power source 62 and supplies it to the power transmission unit 21 of the power transmission device 11B. The power transmission unit 21 of the power transmission device 11B supplies power to the power reception unit 221 of the power reception device 220 mounted on the vehicle 200 in a non-contact manner by the converted electric power. Further, the control unit 40 of the power transmission device 11B transmits the power received from the power source 62 to the power transmission device 10B without converting it. The electric power transmitted to the power transmission device 10B is reduced by the amount of the electric power supplied to the power transmission unit 21 of the power transmission device 11B from the power received from the power source 62.
　送電装置１０Ｂの制御部４０は、送電装置１１Ｂから受電した変換されていない電力を変換するが、送電装置１０Ｂの送電部２１には電力を供給しない。したがって、送電装置１０Ｂの送電部２１は、車両２００に搭載された受電装置２２０の受電部２２１に電力を供給しない。また、送電装置１０Ｂの制御部４０は、変換されていない電力を送電装置１２Ｂに送電する。送電装置１２Ｂに送電される電力は、送電装置１１Ｂから受電した電力から、送電装置１０Ｂの送電部２１に供給された電力の分だけ減ることになるが、送電装置１０Ｂの送電部２１に供給される電力はゼロなので、送電装置１２Ｂに送電される電力は、送電装置１１Ｂから受電した電力に等しい。上記のように、送電装置１０Ｂは、他の送電装置１１Ｂと送電装置１２Ｂとの間の電路として機能する。 The control unit 40 of the power transmission device 10B converts the unconverted power received from the power transmission device 11B, but does not supply power to the power transmission unit 21 of the power transmission device 10B. Therefore, the power transmission unit 21 of the power transmission device 10B does not supply electric power to the power reception unit 221 of the power reception device 220 mounted on the vehicle 200. Further, the control unit 40 of the power transmission device 10B transmits the unconverted electric power to the power transmission device 12B. The power transmitted to the power transmission device 12B is reduced by the amount of the power supplied to the power transmission unit 21 of the power transmission device 10B from the power received from the power transmission device 11B, but is supplied to the power transmission unit 21 of the power transmission device 10B. Since the power is zero, the power transmitted to the power transmission device 12B is equal to the power received from the power transmission device 11B. As described above, the power transmission device 10B functions as an electric line between the other power transmission device 11B and the power transmission device 12B.
　送電装置１２Ｂの制御部４０は、送電装置１０Ｂから受電した変換されていない電力を変換して送電装置１２Ｂの送電部２１に供給する。変換された電力により送電装置１２Ｂの送電部２１は、車両２００に搭載された受電装置２２０の受電部２２１に非接触で電力を供給する。送電装置１０Ｂ，１１Ｂ，１２Ｂは、上記第２実施形態の道路床版１００Ｂに取り付けられてもよい。 The control unit 40 of the power transmission device 12B converts the unconverted power received from the power transmission device 10B and supplies it to the power transmission unit 21 of the power transmission device 12B. The power transmission unit 21 of the power transmission device 12B supplies power to the power reception unit 221 of the power reception device 220 mounted on the vehicle 200 in a non-contact manner by the converted electric power. The power transmission devices 10B, 11B, and 12B may be attached to the road deck 100B of the second embodiment.
　本実施形態によれば、制御部４０により、送電部２１によって受電部２２１に非接触で供給する電力が変更可能に制御される。このため、路面Ｓに沿って設置されて互いに電気的に連結された当該送電装置１０Ｂ及び他の送電装置１１Ｂ，１２Ｂのそれぞれで送電部２１により受電部２２１に非接触で供給する電力を変更でき、非接触給電時の利便性が向上する。 According to the present embodiment, the control unit 40 is able to changeably control the power supplied to the power receiving unit 221 by the power transmission unit 21 in a non-contact manner. Therefore, the power supplied to the power receiving unit 221 by the power transmission unit 21 can be changed in each of the power transmission device 10B and the other power transmission devices 11B and 12B installed along the road surface S and electrically connected to each other. , Convenience at the time of non-contact power supply is improved.
　公共の場所では、複数の非接触給電装置を敷設し、複数の非接触給電装置のそれぞれを同時に独立して制御する必要がある場合がある。本実施形態では、複数の送電装置１０Ｂ、１１Ｂ，１２Ｂのそれぞれが制御部４０を有しており、それらを同時に独立して制御することができ、送電装置１０Ｂ、１１Ｂ，１２Ｂの設置後の利便性が向上する。例えば、車両２００一台ごとに異なる電力を非接触給電することができる。また、本実施形態では、例えば、車両２００の接近に応じて、送電装置１０Ｂ、１１Ｂ，１２Ｂの中で必要な送電部２１のみに通電することができ、消費電力を低減できる。 In public places, it may be necessary to install multiple contactless power supply devices and control each of the multiple contactless power supply devices at the same time independently. In the present embodiment, each of the plurality of power transmission devices 10B, 11B, 12B has a control unit 40, which can be controlled independently at the same time, which is convenient after installation of the power transmission devices 10B, 11B, 12B. Sex improves. For example, different electric power can be non-contactly supplied to each vehicle 200. Further, in the present embodiment, for example, according to the approach of the vehicle 200, only the necessary power transmission unit 21 in the power transmission devices 10B, 11B, 12B can be energized, and the power consumption can be reduced.
　また、本実施形態では、例えば、送電装置１０Ｂ上が非接触給電機能を有しない車両、例えばガソリンエンジン車のための駐車場である場合に、送電装置１０Ｂの送電部２１に電力が供給されず、送電装置１０Ｂを他の送電装置１１Ｂと送電装置１２Ｂとの間の電路として機能させることができる。また、本実施形態によれば、制御部４０は、送電部２１の側方に配置されているため、設置後における送電装置１０Ｂ，１１Ｂ，１２Ｂの保守が容易となる。 Further, in the present embodiment, for example, when the power transmission device 10B is a parking lot for a vehicle having no contactless power supply function, for example, a gasoline engine vehicle, power is not supplied to the power transmission unit 21 of the power transmission device 10B. , The power transmission device 10B can function as an electric line between another power transmission device 11B and the power transmission device 12B. Further, according to the present embodiment, since the control unit 40 is arranged on the side of the power transmission unit 21, maintenance of the power transmission devices 10B, 11B, 12B after installation becomes easy.

The power transmission system 1000E of the present embodiment is configured by connecting a plurality of road decks 100B in a line with each other. In the example of FIG. 13, the control units 40 of the power transmission devices 10D, 11D, and 12D individually respond to the approach of the object detected by the sensor unit 50, and the power transmission units of the power transmission devices 10D, 11D, and 12D, respectively. 21 controls the power supplied to the power receiving unit 221 in a non-contact manner so as to be changeable.
　図１３においては、変換されていない交流電力は破線で示され、変換された交流電力は実線で示される。送電装置１０Ｄ，１１Ｄ，１２Ｄのそれぞれの制御部４０は、センサ部５０により車両２００の接近が検知されたときのみ、送電装置１０Ｄ，１１Ｄ，１２Ｄのそれぞれの送電部２１に電力を供給する。送電装置１０Ｄ，１１Ｄ，１２Ｄのそれぞれの制御部４０は、センサ部５０により車両２００の接近が検知されていないときは、送電装置１０Ｄ，１１Ｄ，１２Ｄのそれぞれの送電部２１に電力を供給しない。 In FIG. 13, the unconverted AC power is shown by a broken line, and the converted AC power is shown by a solid line.
