Zusammenfassung: | The present invention relates to a planar transformer. According to the present invention, a transformer includes: an upper primary substrate (110) which is formed by stacking a plurality of dielectric substrates in which conductive patterns are formed in spiral; a primary lower secondary substrate (120) which is positioned below the upper primary substrate (110) in such a way that the lower secondary substrate comes into contact with the upper primary substrate (110) or is spaced apart from the upper primary substrate (110) and is formed by stacking a plurality of dielectric substrates in which the conductive patterns are formed in spiral; and a secondary coil element (200) of a planar shape to generate an induced current by a current applied to the upper primary substrate (110) and the lower primary substrate (120). Therefore, the generation of magnetic loss field is reduced, and the efficiency from the primary side to the secondary side is increased.
본 발명은 평판형 변압기에 관한 것으로, 본 발명에 의하면, 도체패턴이 나선상으로 형성된 절연기판이 복수로 적층 구비되어 있는 1차측 상부 기판(110)과, 상기 1차측 상부 기판(110)의 하방에서 상기 1차측 상부 기판(110)과 접촉하거나 또는 이격되도록 위치하며, 도체패턴이 나선상으로 형성된 절연기판이 복수로 적층 구비되어 있는 1차측 하부 기판(120)과, 상기 1차측 상부 기판(110)과 1차측 하부 기판(120)에 인가되는 전류에 의해서 유도전류가 발생되는 평판상의 2차측 코일소자(200)를 포함하여 구성되는 것을 특징으로 하고, 이에 의하면 손실 자계의 발생이 작아져서 1차측에서 2차측으로의 효율이 높아지는 이점이 있다. |
