【発明の実施の形態】以下、本発明の実施の形態について、図1から図8を用いて説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to FIGS 1.

【0007】(実施の形態1)図1は本発明の非接触型電源装置の構成図であり、図1において1は1次コイルであり、1次コア10、第1の1次巻線11、第2の1 [0007] (Embodiment 1) FIG. 1 is a block diagram of a contactless power supply device of the present invention, 1 is the primary coil in Figure 1, the primary core 10, first primary winding 11 , the second of 1
次巻線12から構成される。 Consisting of winding 12. 1次コア10はO形の閉磁路であり、対向する磁脚にそれぞれ1次巻線11及び1 The primary core 10 is a closed magnetic circuit of the O-shaped, respectively magnetic legs facing primary winding 11 and 1
2が巻線され、1次巻線11及び12は直列に接続されている。 2 is wound, the primary winding 11 and 12 are connected in series. 2は2次コイルであり、2次コア20と2次巻線21から構成されている。 2 is a secondary coil, and a secondary core 20 and secondary winding 21. 2次コア20はI形であり、これに2次巻線21が巻線されている。 Secondary core 20 is I-shaped, which in the secondary winding 21 is wound. 3は高周波交流電源であり、1次コイル1に接続され、高周波電流を供給する。 3 is a high-frequency AC power source, connected to the primary coil 1, which supplies a high-frequency current. 4は整流回路であり、2次コイル2に接続され、2次コイル2に誘起される高周波交流電圧を整流し、直流出力電圧として負荷5に供給する。 4 is a rectifying circuit, connected to the secondary coil 2, is induced in the secondary coil 2 rectifies the high-frequency AC voltage, supplied to the load 5 as a DC output voltage. 6は電流制限回路であり、高周波交流電源3から1次コイル1へ供給される電流が過大とならないように制限する。 6 is a current limiting circuit, the current supplied from the high-frequency AC power supply 3 to the primary coil 1 is limited not become excessive. また、 Also,
図2は2次コイル2が対向していない時の構成図である。 Figure 2 is a configuration diagram when the secondary coil 2 is not opposed.

【0008】以上のように構成された非接触型電源装置について、以下にその動作を述べる。 [0008] The non-contact power supply device configured as described above will be described the operation below. 高周波交流電源3 High-frequency AC power supply 3
から供給された高周波電流は第1の1次巻線11と第2 Supplied from the high-frequency current to the first primary winding 11 second
の1次巻線12を流れる。 Flowing through the primary winding 12 of. この高周波電流が図1の矢印の向きの時、第1の1次巻線11による磁束は1次コア10の中の実線で示すように発生する。 When this high-frequency current of a direction indicated by an arrow in FIG. 1, the magnetic flux of the first primary winding 11 generates as shown by the solid line in the primary core 10. 同様に第2の1 Similarly, the second of 1
次巻線12による磁束は1次コア10の中の破線で示すように発生し、これらの磁束は2次コア20を通る。 Magnetic flux by the primary winding 12 is generated as shown by the broken line in the primary core 10, these magnetic flux passes through the secondary core 20. このため2次コイル2には電圧が誘起され、整流回路4を介して負荷5へ供給される。 Thus a voltage is induced in the secondary coil 2, it is supplied via the rectifier circuit 4 to the load 5.

【0009】次に、図2のように2次コイル2が対向していない場合、高周波電流が図2の矢印の向きの時、第1の1次巻線11による磁束は1次コア10の中の実線で示すように発生する。 [0009] Then, if the secondary coil 2 as shown in FIG. 2 does not face, a high frequency current when the arrow direction of FIG. 2, the magnetic flux of the first primary winding 11 of the primary core 10 It occurs as indicated by the solid line in. 同様に第2の1次巻線12による磁束は1次コア10の中の破線で示すように発生し、 Similarly the flux according to the second primary winding 12 is generated as shown by the broken line in the primary core 10,
これらの磁束は互いに打ち消し合う。 These magnetic flux cancel each other out. このため1次コイル1は短絡状態となり、電流制限回路6が動作して高周波交流電源3からの電流を制限する。 Thus the primary coil 1 becomes a short-circuited state, limits the current from the high-frequency AC power supply 3 current limiting circuit 6 operates. この時、1次コイル1に発生する磁束は前記の通り打ち消し合う上、1次コア10が閉磁路であるため漏洩磁束はほとんど発生しない。 At this time, on the magnetic flux generated in the primary coil 1 is canceled out as the primary core 10 flux leakage hardly occurs because a closed magnetic path.

【0010】なお、図1に示したように、1次コイル1 [0010] Incidentally, as shown in FIG. 1, the primary coil 1
のO形コア内にI形の2次コイル2が挿入できるような構造は、筐体も含む非接触型電源装置全体の形状的制約から困難な場合が多い。 Structure as the secondary coil 2 can be inserted in the I-shaped in O-shaped core is often difficult from the non-contact type power supply device overall shape constraints also includes housing. しかし非接触型電源装置の1次側と2次側がそれぞれの平面状の対向する筐体面71及び72を有する場合として、図3に示すような構造でも本発明は実施可能である。 However, as a case where the primary side and the secondary side of the non-contact type power supply device having a housing surface 71 and 72 facing each planar, the invention in the structure shown in FIG. 3 can be carried out. 図3(a)は構造図、(b) 3 (a) is structural view, (b)
及び(c)はそれぞれその正面図と側面図である。 And (c) is a front view and a side view respectively. 煩雑になるので(a)では筐体面71及び72は省略した。 Since complicated in (a) the housing surface 71 and 72 are omitted.

【0011】なお、1次コイル1に高周波電流を供給する手段を高周波交流電源3として説明したが、図4に示すように、入力直流電源30とスイッチング手段31とで構成し、入力直流電源30の直流電圧をスイッチング手段31が高周波でチョッピングしても実施可能である。 [0011] Note that a means for supplying a high-frequency current to the primary coil 1 has been described as a high frequency AC power source 3, as shown in FIG. 4, constituted by an input DC power supply 30 and switching means 31, the input DC power supply 30 also a DC voltage by chopping switching means 31 at a high frequency can be implemented.

【0012】なお、2次コイル2が対向していない場合に、1次コイル1に流れる高周波電流を制限する手段として電流制限回路6を用いて説明したが、例えば図5 [0012] In the case where the secondary coil 2 does not face, it has been described using a current limiting circuit 6 as a means for limiting the high-frequency current flowing through the primary coil 1, for example, FIG. 5
(a)のように抵抗60のような電流検出手段で高周波電流を検出し、電流が所定値以上になろうとすると、トランジスタ61によってスイッチング手段31をオフするような方法がある。 Detecting a high-frequency current by the current detecting means such as resistor 60 as (a), when the current is to become a predetermined value or more, there is a method to turn off the switching means 31 by the transistor 61. これ以外の電流制限回路でも実施可能である。 It can be implemented in other current limiting circuit. さらに図5(b)に示したように1次コイル1と直列にインダクタ62を接続し、2次コイル2が対向していない場合に、1次コイル1が短絡状態となってインダクタ62に入力電圧が印加されることを検出回路63で検出してスイッチング手段31をオフするような方法もある。 Further connecting the primary coil 1 and the series inductor 62 as shown in FIG. 5 (b), when the secondary coil 2 does not face the input to the inductor 62 and the primary coil 1 becomes short-circuited there is also such a way as to turn off the switching means 31 is detected by the detecting circuit 63 a voltage is applied. 1次コイル1が短絡状態となることを利用して、2次コイル2が対向していない状態を検出できることが本発明の効果の一つである。 By utilizing the fact that the primary coil 1 is short-circuited, it can detect the state where the secondary coil 2 does not face is one of the advantages of the present invention.
