At this time, Figure 1 is a projection of the transformer and the primary coil provided in the case of the contactless power transmitter and projected.

본 발명에 따른 무접점 송수신기는 도 1 내지 도 3에 도시된 바와 같이, 1차 코일(120)과, 1차 코일(120)의 일면에 구비된 제 1 퍼멀로이(110)와, 1차 코일(120)에 전압을 인가하는 변압기(130)를 포함한다. 또한, 1차 코일(120)에서 유도된 자기장에 의해 전류를 생성하는 2차 코일(220)을 포함한다. 또한, 변압기(130)에 외부 전원을 공급하는 배선(140)을 포함한다.1 to 3, the contactless transceiver according to the present invention, the primary coil 120, the first permalloy 110 provided on one surface of the primary coil 120, and the primary coil ( And a transformer 130 for applying a voltage to the 120. It also includes a secondary coil 220 that generates a current by the magnetic field induced by the primary coil 120. In addition, a wiring 140 for supplying external power to the transformer 130 is included.

변압기(130)는 1차 코일(120)에 전원을 공급하기 위한 것으로서, 본 실시예는 변압기(130)로 가변 전압 조정기 중 가변 교류 단권변압기(Variable AC Autotransformer), 즉, 슬라이닥스(SLIDE-AC)를 예시한다. 또한, 가변 교류 단권변압기를 이용하여 높은 교류 전류를 발생시키고, UC3879, IR2110, IRF540 등을 이용하여 고주파 신호 발생시킨다.Transformer 130 is for supplying power to the primary coil 120, this embodiment is a variable AC regulator (Variable AC Autotransformer), that is, the SLIDE-AC of the variable voltage regulator to the transformer 130 ). In addition, a high AC current is generated using a variable AC single winding transformer, and a high frequency signal is generated using UC3879, IR2110, IRF540, and the like.

본 실시예는 가변 교류 단권변압기가 0 내지 240V의 전압을 1차 코일(120)에 공급하는 것을 예시한다. 하지만 이에 한정되는 것은 아니며, 충전 대상물(200)의 변경에 따라 가변 교류 단권변압기의 출력 전압은 변경될 수 있다.This embodiment illustrates that the variable AC single winding transformer supplies a voltage of 0 to 240V to the primary coil 120. However, the present invention is not limited thereto, and the output voltage of the variable AC single winding transformer may be changed according to the change of the charging target 200.

1차 코일(120)은 변압기(130)에서 공급된 전원을 이용하여 자기장을 발생시키기 위한 것으로서, 본 실시예는 가격이 저렴하고 가공이 용이하며 종류가 다양한 애나멜 코일을 1차 코일(120)로 사용한다. 물론, 1차 코일(120)은 애나멜 코일만을 포함하는 것은 아니며, 본 발명의 목적에 부합하는 모든 코일을 1차 코일(120)로 사용할 수 있다. 또한, 1차 코일(120)은 똬리형상, 즉, 형으로 얇고 넓게 감긴 형상으로서, 이러한 형상에 의해 1차 코일(120)은 주파수 별로 높은 전류 및 전압 전달 효율을 가질 수 있다.Primary coil 120 is to generate a magnetic field using the power supplied from the transformer 130, this embodiment is a low-cost, easy to process and various types of enameled coil to the primary coil 120 use. Of course, the primary coil 120 does not include only an enamel coil, and all coils meeting the object of the present invention may be used as the primary coil 120. In addition, the primary coil 120 is in a thin shape, that is, a thin and wide wound shape, the primary coil 120 by this shape can have a high current and voltage transfer efficiency for each frequency.

제 1 퍼멀로이(110)는 1차 코일(120)과 함께 자기장을 발생시키기 위한 것으로서, 퍼멀로이(Permalloy)를 포함한다. 퍼멀로이는 니켈과 철의 이원합금으로서, 열처리에 의해 높은 자기투과도를 나타내며 이에 따라 약한 자기장 속에서 높은 반응을 나타낸다. 이러한 성질에 의해 제 1 퍼멀로이(110)는 1차 코일(120)의 자기장을 증폭하여 1차 코일(120)과 2차 코일(220)이 일정거리 이격되어도 2차 코일(220)에 전류를 유도할 수 있다. 물론, 이러한 퍼멀로이에는 크롬, 몰리브덴, 티탄 등이 더 추가될 수도 있다.The first permalloy 110 is to generate a magnetic field together with the primary coil 120 and includes a permalloy. Permalloy is a binary alloy of nickel and iron, which exhibits high magnetic permeability by heat treatment and therefore high reaction in weak magnetic fields. Due to this property, the first permalloy 110 amplifies the magnetic field of the primary coil 120 to induce a current in the secondary coil 220 even when the primary coil 120 and the secondary coil 220 are separated by a predetermined distance. can do. Of course, chromium, molybdenum, titanium, or the like may be further added to the permalloy.

퍼멀로이는 페라이트보다 더 얇고 가벼우며, 이에 따라 이러한 퍼멀로이를 사용한 본 발명에 따른 무접점 전력송수신기는 휴대가 용이하며 사용이 편리하다. 또한, 퍼멀로이는 원하는 모양으로 가공이 용이하여 작은 패드의 형태로 제작이 가능하여, 무접점 전력송수신기를 제작하기 용이하다.The permalloy is thinner and lighter than ferrite, and thus the contactless power transmitter according to the present invention using such permalloy is portable and convenient to use. In addition, permalloy is easy to process the desired shape can be manufactured in the form of a small pad, it is easy to manufacture a contactless power transmitter.

또한, 이러한 퍼멀로이는 도 4에 도시된 바와 같이, 유효투자율이 고주파수로 갈수록 낮아지는 것을 알 수 있다. 또한, 도 4는 퍼멀로이의 두께가 0.025mm인 경우로서, 본 실시예와 같이 퍼멀로이의 두께를 2mm로 할 경우 해당 그래프 수치가 훨씬 더 높아진다. 따라서, 이와 같은 퍼멀로이를 사용한 본 발명에 따른 무접점 송수신기는 1차 코일(120)과 2차 코일(220)이 이격되어 있어도 전력 송수신이 가능하다.In addition, such a permalloy can be seen that the effective permeability is lowered toward the higher frequencies, as shown in FIG. In addition, FIG. 4 is a case where the thickness of the permalloy is 0.025 mm, and when the thickness of the permalloy is 2 mm as in the present embodiment, the graph value becomes much higher. Therefore, the contactless transceiver according to the present invention using such a permalloy can transmit and receive power even when the primary coil 120 and the secondary coil 220 are spaced apart from each other.

본 실시예는 평면도를 기준으로 제 1 퍼멀로이(110)가 소정두께를 갖는 사각판 형상을 예시한다. 하지만 이에 한정되는 것은 아니며, 제 1 퍼멀로이(110)는 소정두께를 갖는 원형, 반원형, 타원형, 반타원형, 다각형의 형상으로 제작될 수 있다. 또한, 본 실시예는 제 1 퍼멀로이(110)가 1차 코일(120)의 일면에만 구비되었으나, 제 1 퍼멀로이(110)는 1차 코일(120)의 일면과 타면 또는 1차 코일(120)의 전체면을 감싸도록 구비될 수도 있다.This embodiment illustrates a rectangular plate shape in which the first permalloy 110 has a predetermined thickness based on the top view. However, the present invention is not limited thereto, and the first permalloy 110 may be manufactured in a circular, semi-circular, elliptical, semi-elliptic, and polygonal shape having a predetermined thickness. In addition, in the present embodiment, the first permalloy 110 is provided only on one surface of the primary coil 120, but the first permalloy 110 may have one surface and the other surface of the primary coil 120 or the primary coil 120. It may be provided to surround the entire surface.

2차 코일(220)은 1차 코일(120)에서 발생된 자기장에 의해 전류를 유도하기 위한 것으로서, 1차 코일(120)과 동일하게 애나멜 코일을 포함할 수 있다. 또한, 2차 코일(220)은 충전 대상물에 구비되어 충전 대상물(200)의 배터리와 전기적으로 접속된다. 이러한 구조에 의해 1차 코일(120)과 제 1 퍼멀로이(110)를 통해 유도된 자기장은 2차 코일(220)로 전달되고, 2차 코일(220)은 전달된 자기장에 의해 전류를 생성한다. 또한, 이와 같이 생성된 전류에 의해 충전 대상물(200)이 충전된다. 또한, 2차 코일(220)은 충전 대상물(200)이 필요한 전압과 전류의 크기에 따라 1차 코일(120)과 권선수가 동일하거나 상이할 수 있다. 또한, 상기에서는 2차 코일(220)이 1차 코일(120)과 동일한 재질과 동일한 형상으로 형성되었으나, 이에 한정되는 것은 아니며, 2차 코일(220)과 1차 코일(120)의 재질과 형상은 서로 상이할 수도 있다. 즉, 2차 코일(220)은 충전 대상물(200)의 형상에 따라 1차 코일(120)과 상이하게 제작되어 충전 대상물(200)에 구비될 수 있다.The secondary coil 220 is to induce a current by the magnetic field generated in the primary coil 120, and may include an enamel coil in the same manner as the primary coil 120. In addition, the secondary coil 220 is provided in the charging object and electrically connected to the battery of the charging object 200. By this structure, the magnetic field induced through the primary coil 120 and the first permalloy 110 is transferred to the secondary coil 220, and the secondary coil 220 generates current by the transmitted magnetic field. In addition, the charging target 200 is charged by the current generated in this way. In addition, the number of turns of the secondary coil 220 may be the same as or different from that of the primary coil 120 according to the magnitude of the voltage and current required for the charging target 200. In addition, in the above, the secondary coil 220 is formed in the same material and the same shape as the primary coil 120, but is not limited thereto, and the material and shape of the secondary coil 220 and the primary coil 120. May be different from each other. That is, the secondary coil 220 may be manufactured differently from the primary coil 120 according to the shape of the charging object 200 and may be provided in the charging object 200.

한편, 본 발명은 2차 코일(220)에 유도되는 자기장의 세기를 증가시키기 위한 제 2 퍼멀로이(미도시)를 더 포함할 수 있다. 이때, 제 2 퍼멀로이(210)는 2차 코일(220) 상에 구비되며, 제 1 퍼멀로이(110)와 동일하게 퍼멀로이(Permalloy)를 포함한다. 또한, 이에 따라 제 2 퍼멀로이(210)는 제 1 퍼멀로이(110)와 함께 1차 코일(120)에서 생성된 자기장의 세기를 증폭하여 2차 코일(220)이 작은 자기장에도 전류를 유도할 수 있도록 한다. 즉, 본 발명은 제 1 퍼멀로이(110)만으로도 1차 코일(120)과 2차 코일(220)이 어느 정도 이격되어도 충전이 가능하나, 충전 대상물(200)에 제 2 퍼멀로이(210)를 구비시켜 충전 가능한 이격거리를 더욱 증가시킬 수 있다. 즉, 본 발명은 충전 대상물이 무접점 전력송수신기 상에 위치하지 않고 무접점 전력송수신기의 주변에 이격되어 위치되더라도 충전이 가능하다.Meanwhile, the present invention may further include a second permalloy (not shown) for increasing the strength of the magnetic field induced in the secondary coil 220. In this case, the second permalloy 210 is provided on the secondary coil 220 and includes the permalloy in the same manner as the first permalloy 110.

That is, in the present invention, the primary coil 120 and the secondary coil 220 may be charged to some extent with only the first permalloy 110, but the second object may be provided with the second permalloy 210 in the object to be charged 200. The charging distance can be further increased. That is, the present invention can be charged even when the object to be charged is not located on the contactless power transmitter, but is spaced apart from the vicinity of the contactless power transmitter.
