The power receiving side matching circuits 23 and 24 are provided in order to efficiently receive power at the power receiving antennas 21 and 22.

本実施形態の受電アンテナ２１、２２は、互いに直交する２軸の放射軸を有しており、送電アンテナ１１、１２から送電される電力を受電可能となっている。送電アンテナ１１、１２と受電アンテナ２１、２２は、所定間隔（本実施形態では５ｃｍ程度）を設けて配置されている。第１受電アンテナ２１は第１送電アンテナ１１と平行に配置され、第１送電アンテナ１１から送電された電力を受電可能となっており、第２受電アンテナ２２は第２送電アンテナ１２と平行に配置され、第２送電アンテナ１２から送電された電力を受電可能となっている。 The power receiving antennas 21 and 22 of the present embodiment have two radiating axes orthogonal to each other, and can receive power transmitted from the power transmitting antennas 11 and 12. The power transmitting antennas 11 and 12 and the power receiving antennas 21 and 22 are arranged with a predetermined interval (about 5 cm in the present embodiment). The first power receiving antenna 21 is disposed in parallel with the first power transmitting antenna 11, and can receive power transmitted from the first power transmitting antenna 11, and the second power receiving antenna 22 is disposed in parallel with the second power transmitting antenna 12. Thus, the power transmitted from the second power transmission antenna 12 can be received.

上記構成の非接触給電装置１は以下のように作動する。まず、インバータ回路１０から超音波モータ２０の駆動周波数と同一周波数（本実施形態では８０ｋＨｚ）の交流電圧を９０°の位相差を設けて出力すると、第１送電アンテナ１１および第２送電アンテナ１２には、それぞれ９０°位相が異なる交流電流（本実施形態では数十ｍＡ）が流れる。 The non-contact power feeding device 1 configured as described above operates as follows. First, when an AC voltage having the same frequency (80 kHz in this embodiment) as the drive frequency of the ultrasonic motor 20 is output from the inverter circuit 10 with a phase difference of 90 °, the first power transmission antenna 11 and the second power transmission antenna 12 are output. , Alternating currents (several tens of mA in the present embodiment) having different phases by 90 ° flow.

受電アンテナ２１、２２では、送電アンテナ１１、１２から送電された電力を電磁誘導によって受電することができる。受電アンテナ２１、２２にて受電した電力は、超音波モータ２０に供給される。つまり、第１受電アンテナ２１および第２受電アンテナ２２から９０°の位相差を持つ交流電圧（周波数８０ｋＨｚ）が超音波モータ２０の入力端子２０ａ、２０ｂに印加されることとなる。これにより、超音波モータ２０が作動し、車両用空調装置１００の吹出口切替ドア１０６が回転軸１０６ａを中心に回動し、空調風の吹出口を切り替えることができる。 The power receiving antennas 21 and 22 can receive the power transmitted from the power transmitting antennas 11 and 12 by electromagnetic induction. The electric power received by the power receiving antennas 21 and 22 is supplied to the ultrasonic motor 20. That is, an AC voltage (frequency 80 kHz) having a phase difference of 90 ° from the first power receiving antenna 21 and the second power receiving antenna 22 is applied to the input terminals 20 a and 20 b of the ultrasonic motor 20. Thereby, the ultrasonic motor 20 operates, the blower outlet switching door 106 of the vehicle air conditioner 100 rotates about the rotation shaft 106a, and the blower outlet of the conditioned air can be switched.

インバータ回路１０の出力をオフにすることで、超音波モータ２０が停止し、吹出口切替ドア１０６の回動が停止する。また、インバータ回路１０の２極の出力端子１０ａ、１０ｂのそれぞれに出力される交流電流の位相を逆（０°→９０°または９０°→０°）にすることで、超音波モータ２０を逆回転させることができ、吹出口切替ドア１０６を反対方向に回動させることができる。 By turning off the output of the inverter circuit 10, the ultrasonic motor 20 is stopped and the rotation of the outlet switching door 106 is stopped. Moreover, the ultrasonic motor 20 is reversed by reversing the phase of the alternating current output to each of the two-pole output terminals 10a and 10b of the inverter circuit 10 (0 ° → 90 ° or 90 ° → 0 °). The outlet switching door 106 can be rotated in the opposite direction.

以上説明した本実施形態によれば、送電側に設けたインバータ回路１０で超音波モータ２０の駆動周波数と同一周波数の交流電圧を出力し、受電側に設けた受電アンテナ２１、２２と超音波モータ２０の入力端子２０ａ、２０ｂを直接接続することで、受電側にはインバータ回路を設ける必要がない。これにより、非接触給電装置１の受電側の構成部品を大幅に削減することができ、低コスト化を図ることができる。 According to the present embodiment described above, the inverter circuit 10 provided on the power transmission side outputs an AC voltage having the same frequency as the drive frequency of the ultrasonic motor 20, and the power receiving antennas 21 and 22 provided on the power receiving side and the ultrasonic motor. By directly connecting the 20 input terminals 20a and 20b, there is no need to provide an inverter circuit on the power receiving side. Thereby, the components on the power receiving side of the non-contact power feeding device 1 can be greatly reduced, and the cost can be reduced.

また、車両用空調装置１００では、空調ダクト１０１等の形状が複雑になり、内部に設けられた超音波モータ２０への配線が難しいことがある。このような場合に、本実施形態の非接触給電装置１を用い、非接触給電で内部の超音波モータ２０に電力供給することが有効である。 Further, in the vehicle air conditioner 100, the shape of the air conditioning duct 101 and the like is complicated, and wiring to the ultrasonic motor 20 provided inside may be difficult. In such a case, it is effective to use the contactless power supply device 1 of the present embodiment and supply power to the internal ultrasonic motor 20 by contactless power supply.
