In addition, the space excluding the area occupied by the first auxiliary winding 8 on the PCB of the ninth layer is occupied by the conductor surface 8-1 connected to the electrical ground of the primary side of the power supply device, and the conductor surface 8 -1) blocks a part of the capacitive coupling that the input winding 7 creates with the second output winding 4.
트랜스포머(6)의 제1출력권선(2)은 다층PCB부(3)의 첫번째 층에 위치하는 제1상쇄권선(10)과 밀착하여 결합하고, 제2출력권선(4)은 열번째 층에 위치하는 제2상쇄권선(11)과 밀착하여 결합한다.The first output winding 2 of the transformer 6 is closely coupled to the first offset winding 10 located on the first layer of the multilayer PCB unit 3, and the second output winding 4 is connected to the tenth layer. It is in close contact with the second offset winding 11 to be coupled.
도 2의 종래의 전원 장치에 있어서, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)은, 모두 동일한 전위의 변동의 극성을 가진다. 제1출력권선(2)과 제2출력권선과 제1상쇄권선(10)과 제2상쇄권선(11)은 입력권선(7)의 전위의 변동의 극성과 반대인 전위의 변동의 극성을 가진다. 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 용량성 결합은 전원 장치의 출력선로(24)가 노이즈 전위를 갖게 한다. 제1상쇄권선(10)과 제2상쇄권선(11)은, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합과 크기는 비슷하고 역 극성인 스위칭 주파수 성분의 용량성 결합을 제1출력권선(2)과 제2출력권선(4)으로 생성시켜서, 전원장치의 1차측의 요소들이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 합을 “영”에 근접시켜서, 전원장치의 선로를 통해서 외부로 미치는 노이즈의 영향을 낮춘다.In the conventional power supply device of Fig. 2, the input winding 7, the first auxiliary winding 8, and the second auxiliary winding 9 all have the same polarity of fluctuation of potential. The first output winding (2), the second output winding, the first offset winding (10) and the second offset winding (11) have a polarity of fluctuation of potential opposite to that of the fluctuation of potential of input winding (7). . The capacitive coupling created by the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9 into the first output winding 2 and the second output winding 4 is the output line of the power supply ( 24) has a noise potential. For the first offset winding 10 and the second offset winding 11, the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9 are the first output winding 2 and the second output. The first output winding (2) and the second output winding (4) generate a capacitive coupling of the switching frequency components that are similar in size and reverse polarity to the capacitive coupling of the switching frequency components generated by the winding (4).

그런데, 도 3의 다층PCB부(3)의 양쪽 끝 층의 PCB 면에 위치하는 제1상쇄권선(10)과 제2상쇄권선(11)은, 권선을 구성하는 도체와 도체 사이에 절연을 위한 간격이 있으며, 이 간격은 도체가 없는 빈 면(10-6 혹은 11-6)을 구성한다. 양쪽 끝 층의 PCB 면의 도체가 없는 빈 면(10-6 혹은 11-6)을 통해서 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 스위칭 주파수 성분의 용량성 결합을 크게 생성한다. 일례로서, 제1상쇄권선(10)과 제2상쇄권선(11)은, 제1출력권선(2)과 제2출력권선(4)의 5턴의 턴 수보다 2배 이상인 11턴의 턴 수를 가지며, 제1출력권선(2)과 제2출력권선(4)으로 역 극성의 스위칭 주파수 성분의 용량성 결합을 생성시켜서, 제1출력권선(2)과 제2출력권선(4)으로 생성되는 스위칭 주파수 성분의 용량성 결합의 합을 “영”에 근접시키려 한다. By the way, the first offset winding 10 and the second offset winding 11 positioned on the PCB surface of both end layers of the multilayer PCB part 3 of FIG. 3 are used for insulation between the conductor constituting the winding and the conductor. There is a gap, which constitutes an empty side (10-6 or 11-6) without conductors. The input winding (7), the first auxiliary winding (8) and the second auxiliary winding (9) are connected to the first output winding ( 2) and the second output winding (4) create a large capacitive coupling of the switching frequency components. As an example, the first offset winding 10 and the second offset winding 11 are the number of turns of 11 turns, which is more than twice the number of turns of 5 turns of the first output winding 2 and the second output winding 4 It has a first output winding (2) and a second output winding (4) by generating a capacitive coupling of the switching frequency component of reverse polarity, the first output winding (2) and the second output winding (4). Try to bring the sum of the capacitive couplings of the switching frequency components to be close to "zero".
도 2의 전원 장치에서, 한 요소로부터 제1출력권선(2)과 제2출력권선(4)으로 생성되는 용량성 결합을 다른 요소가 제1출력권선(2)과 제2출력권선(4)으로 생성하는 역 극성의 용량성 결합에 의해 상쇄시키더라도, 두 개의 다른 요소가 각각 제1출력권선(2)과 제2출력권선(4)으로 생성하는 용량성 결합의 크기가 완전히 일치할 수 없고, 두 개의 다른 요소가 각각 생성하는 용량성 결합의 크기도 제품마다 편차가 있기 때문에, 제품에 따라 상쇄가 이루어진 후의 용량성 결합의 잔량이 클 수 있다. 상쇄가 이루어진 후의 용량성 결합의 잔량은, 한 요소가 제1출력권선(2)과 제2출력권선(4)으로 생성하는 용량성 결합의 크기가 클수록 커질 수밖에 없다.In the power supply of Fig. 2, the capacitive coupling generated from one element to the first output winding (2) and the second output winding (4) is divided into the first output winding (2) and the second output winding (4). Even if canceled by the reverse polarity capacitive coupling produced by the two different elements, the size of the capacitive coupling produced by the first output winding (2) and the second output winding (4), respectively, cannot be completely matched. In addition, since the size of the capacitive bonds generated by the two different elements, respectively, varies from product to product, the remaining amount of capacitive bonds after the offset is made may be large depending on the product. The remaining amount of capacitive coupling after cancellation is inevitably increased as the size of the capacitive coupling generated by one element into the first output winding 2 and the second output winding 4 increases.
그런데, 도 2의 전원 장치에서, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 크기가 상당히 크다. 그러므로, 제1상쇄권선(10)과 제2상쇄권선(11)이 생성하는 역 극성의 용량성 결합에 의해 상쇄가 이루어진 후의 스위칭 주파수 성분의 용량성 결합의 잔량도 당연히 크며, 이러한 다층PCB부(3)를 사용하는 전원 장치는 외부에 스위칭 주파수 성분의 노이즈의 영향을 크게 미치게 되는 단점을 가진다.By the way, in the power supply device of Fig. 2, the input winding 7, the first auxiliary winding 8, and the second auxiliary winding 9 are the switching generated by the first output winding (2) and the second output winding (4). The size of the capacitive coupling of the frequency components is quite large. Therefore, the residual amount of the capacitive coupling of the switching frequency component after cancellation by the reverse polarity capacitive coupling generated by the first offset winding 10 and the second offset winding 11 is naturally large, and such a multilayer PCB unit ( The power supply using 3) has the disadvantage of having a large influence of the noise of the switching frequency component on the outside.
또한, 도 2의 전원 장치에서, 제1상쇄권선(10)과 제2상쇄권선(11)은, 자체의 분포용량과 Leakage Inductance등의 영향에 의해, 입력권선(7)의 전압에 비해 위상이 지연된 전압을 갖는다. 제1상쇄권선(10)과 제2상쇄권선(11)의 전압에 포함되는 고주파 성분의 전압의 파형은, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)의 전압에 포함되는 고주파 성분의 전압 파형과 다르다. 그로 인해, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 다른 파형의 고주파 성분의 용량성 결합은 제1상쇄권선(10)과 제2상쇄권선(11)이 생성하는 용량성 결합에 의해 상쇄시키지 못한다. 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합과 그 용량성 결합에 포함된 고주파 성분의 용량성 결합이 상당히 크므로, 상쇄시키지 못하는 고주파 성분의 용량성 결합도 상당히 커진다. 그로 인해, 전원 장치의 출력 선로(24)는 매우 큰 고주파 노이즈의 전위를 가지게 된다. 따라서, 도 3의 다층PCB부(3)를 사용하는 전원장치는 외부에 고주파 성분의 노이즈의 영향을 크게 미치게 되는 단점을 가진다.In addition, in the power supply device of FIG. 2, the first offset winding 10 and the second offset winding 11 are in phase compared to the voltage of the input winding 7 due to the influence of their own distribution capacity and leakage inductance. It has a delayed voltage. The waveform of the voltage of the high-frequency component included in the voltages of the first offset winding 10 and the second offset winding 11 is the waveform of the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9. It is different from the voltage waveform of the high-frequency component included in the voltage. Therefore, the capacity of the high-frequency components of different waveforms generated by the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9 by the first output winding 2 and the second output winding 4 Sexual coupling cannot be canceled by capacitive coupling generated by the first offset winding 10 and the second offset winding 11. The capacitive combination of the switching frequency components generated by the input winding (7), the first auxiliary winding (8) and the second auxiliary winding (9) as the first output winding (2) and the second output winding (4) and their capacity Since the capacitive coupling of the high-frequency component included in the sexual coupling is considerably large, the capacitive coupling of the high-frequency component that cannot be canceled is also considerably large. Therefore, the output line 24 of the power supply device has a potential of very large high-frequency noise. Accordingly, the power supply device using the multilayer PCB unit 3 of FIG. 3 has a disadvantage in that external noise of high-frequency components is greatly influenced.
또한, 도 2의 종래의 전원장치에 사용되는 트랜스포머(6)는, 제1보조권선(8)과 제2보조권선(9)과 제1상쇄권선(10)과 제2상쇄권선(11)이 입력권선(7)과 제1출력권선(2)과 제2출력권선(4) 사이의 거리를 증가시켜서 자기적인 결합을 방해하여 Leakage inductance를 높이며, 전력 효율을 낮추는 단점을 가진다.In addition, the transformer 6 used in the conventional power supply device of FIG. 2 includes a first auxiliary winding 8, a second auxiliary winding 9, a first offset winding 10, and a second offset winding 11. By increasing the distance between the input winding 7 and the first output winding 2 and the second output winding 4, magnetic coupling is prevented, thereby increasing leakage inductance and lowering power efficiency.
한편, 종래의 기술에서 도 3의 다층PCB부(3)의 층 수를 낮출 수 있는 여지가 있는지 살펴본다.Meanwhile, it will be looked at whether there is room for reducing the number of layers of the multilayer PCB unit 3 of FIG. 3 in the prior art.
다층 PCB의 도체 면에 의해 입력권선(7)을 구성하는 경우, 입력권선(7)을 통해서 흐르는 전류의 크기를 감안하여 입력권선(7)을 구성할 도체의 두께와 폭과 도체 사이의 간격 등을 결정하여야 하는데, 1 층의 PCB면에 대략 8 턴 정도가 감길 수 있다. 예를 들어, 입력권선(7)의 턴 수가 40 턴인 경우, 1층에 8턴씩 구성할 수 있으므로, 5층의 PCB 면이 필요하다. 제1상쇄권선(10)과 제2상쇄권선(11)을 위해 2 층의 PCB 면이 필요하다. 보조권선(8과 9)을 위해 최소한 1 층의 PCB 면이 필요하다. 또한, 홀수로 구성되는 입력권선(7)과 보조권선(8과 9)의 한 끝을 트랜스포머(6)의 단자로 연결할 1 층의 PCB 면이 필요하다. 그래서, 최소로 구성할 수 있는 적층 PCB의 층 수는 총 9층이다. 그런데, 다층PCB부는, 모든 층을 Through Hole에 의해 연결되게 하기 위하여, 복수의 양면 PCB를 붙여서 제작되며, 짝수 층으로 이루어진다. 따라서, 최소로 구성할 수 있는 적층 PCB의 층 수는 총 10층이며, 한 층의 PCB 면을 활용할 여유가 있다.In the case of configuring the input winding 7 by the conductor surface of the multilayer PCB, the thickness and width of the conductor that will constitute the input winding 7 and the gap between the conductors, etc., in consideration of the magnitude of the current flowing through the input winding 7 It should be determined, and it can be wound around 8 turns on the first layer of the PCB. For example, if the number of turns of the input winding 7 is 40 turns, it is possible to configure 8 turns per layer, and thus a 5-layer PCB surface is required. A two-layer PCB surface is required for the first offset winding 10 and the second offset winding 11. At least one layer of PCB side is required for the auxiliary windings (8 and 9). In addition, a one-layer PCB surface is required to connect one end of the input winding 7 and the auxiliary windings 8 and 9 composed of odd numbers to the terminals of the transformer 6. So, the minimum number of layers of a laminated PCB that can be configured is a total of 9 layers. By the way, the multilayer PCB part is manufactured by attaching a plurality of double-sided PCBs in order to connect all layers by a through hole, and consists of an even number of layers. Therefore, the minimum number of layers of the laminated PCB that can be configured is 10 layers, and there is room to use one layer of the PCB.
도 2에 사용되는 도 3의 다층PCB부(3)는, 입력권선(7)을 6층의 PCB 면에 구성하였고, 보조권선을 제1보조권선(8)과 제2보조권선(9)으로 나누어 2층의 PCB면에 구성하였고, 제1상쇄권선(10)과 제2상쇄권선(11)을 2층의 PCB면에 구성하였으므로, 총 10층의 PCB면을 가진다. 그에 따라, 입력권선(7)은, 일 실시예에 있어서, 1 층에 7턴씩 구성되어, 6 층의 PCB면에 42턴으로 구성된다.In the multilayer PCB unit 3 of FIG. 3 used in FIG. 2, the input winding 7 is formed on the 6-layer PCB surface, and the auxiliary windings are divided into a first auxiliary winding 8 and a second auxiliary winding 9. Divided into a two-layer PCB surface, the first offset winding 10 and the second offset winding 11 are configured on the two-layer PCB surface, thus having a total of 10 layers of the PCB surface. Accordingly, the input winding 7 is configured by 7 turns per layer in one embodiment, and by 42 turns per 6-layer PCB surface.
이와 같이 도 2의 종래의 전원장치에 사용되는 트랜스포머(6)는, 총 10층의 PCB 면을 가지는 높은 가격의 다층 PCB(3)를 포함하며, 전원장치의 제조 원가를 높이는 단점을 가진다.As described above, the transformer 6 used in the conventional power supply device of FIG. 2 includes a high-priced multilayer PCB 3 having a total of 10 layers of PCB, and has a disadvantage of increasing the manufacturing cost of the power supply device.
종래 기술의 샌드위치 권선 구조를 갖는 평면형 트랜스포머의 다층PCB부는, 전원장치의 1차측의 많은 구성 요소들을 포함하여야 했기 때문에 10 층의 PCB의 면이 필요하여 고가이고, 전원장치의 제조 원가를 높이는 단점을 가진다. 또한, 종래의 전원장치에 사용되는 트랜스포머(6)의 다층PCB부(3)의 제1보조권선(8)과 제2보조권선(9)과 제1상쇄권선(10)과 제2상쇄권선(11)은 입력권선(7)의 Leakage inductance를 높이며, 전원 장치의 손실을 증가시켜서 전력 효율을 낮추는 단점을 가진다. 또한 종래의 전원장치에 사용되는 트랜스포머(6)의 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 용량성 결합이 커서, 전원 장치가 외부로 스위칭 주파수 성분 및 고주파 성분의 노이즈의 영향을 크게 미치는 단점을 가진다.The multilayer PCB part of a planar transformer with a sandwich winding structure of the prior art has to include many components on the primary side of the power supply, so it requires a 10-layer PCB, which is expensive, and increases the manufacturing cost of the power supply. Have. In addition, the first auxiliary winding 8 and the second auxiliary winding 9 and the first offset winding 10 and the second offset winding of the multilayer PCB unit 3 of the transformer 6 used in the conventional power supply device ( 11) has a disadvantage of increasing the leakage inductance of the input winding 7 and lowering power efficiency by increasing the loss of the power supply device. In addition, the input winding (7), the first auxiliary winding (8) and the second auxiliary winding (9) of the transformer (6) used in the conventional power supply device is the first output winding (2) and the second output winding (4). Since the capacitive coupling generated by the power supply is large, the power supply device has a disadvantage that greatly affects the noise of the switching frequency component and the high frequency component to the outside.
본 발명은 종래 기술의 이러한 단점들을 모두 해결하기 위한 것이다.The present invention is to solve all of these drawbacks of the prior art.

It is 30% smaller than 6). Therefore, the capacitive coupling of the switching frequency components generated from the first input winding 25 to the second output winding 4-1 through the blank surface 26-6 without a conductor is a blank surface without a conductor in FIG. It is much smaller than the capacitive combination of the switching frequency components generated from the input winding (7) and the first auxiliary winding (8) and the second auxiliary winding (9) to the second output winding (4) through (11-6). . In addition, the first coupling portion 27-1 connected to the electrical ground of the primary side of the power supply and the second coupling portion 27- connected to the starting point of the second winding 26-2 of the second input winding 26. 2) occupies most of the PCB surface of the first layer of the multilayer PCB part 3-1 of FIG. 5, and the first input winding 25 is the first output winding 2-1, which is capacitive. Effectively block the combination of Therefore, the first input winding 25 hardly generates a capacitive coupling of the switching frequency components to the first output winding 2-1. Therefore, the capacitiveness of the switching frequency component generated by the first input winding 25 as the first output winding 2-1 and the second output winding 4-1 in the multilayer PCB unit 3-1 of FIG. 5 In the multilayer PCB part 3 of FIG. 3, the input winding 7, the first auxiliary winding 8, and the second auxiliary winding 9 have the first output winding 2 and the second output winding ( It is about 1/4 of the size of the capacitive coupling of the switching frequency component generated by 4).

Even if the voltage of the second coupling portion 27-2 and the third coupling portion 28 differs from the first input winding 25 in the waveform of the voltage of the high-frequency component due to the phase delay, the first coupling portion The first input winding 25 and the first output winding that cannot be canceled by the capacitive coupling of reverse polarity generated by the (27-1), the second coupling portion 27-2, and the third coupling portion 28 The size of the capacitive coupling of the high frequency component between 2-1) and the second output winding 4-1 is also much smaller.

도 22의 다층PCB부(3-17)의 일 실시예에 있어서, In an embodiment of the multilayer PCB unit 3-17 of FIG. 22,
전원 장치의 1차측의 전기적인 접지의 전위를 가지는 제1결합부(43-1)는 제1입력권선(25)으로부터 제1출력권선(2-1)으로 생성되는 스위칭 주파수 성분의 용량성 결합과 같은 극성의 스위칭 주파수 성분의 용량성 결합을 제1출력권선(2-1)으로 생성한다. 상쇄권선(44)의 시작점의 전위가 연결된 제2결합부(43-2)는 제1입력권선(25)으로부터 제1출력권선(2-1)으로 생성되는 스위칭 주파수 성분의 용량성 결합과 반대 극성의 스위칭 주파수 성분의 용량성 결합을 제1출력권선(2-1)으로 생성한다. 그러나, 제1결합부(43-1)와 제2결합부(43-2)의 차단에 의해 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)은 제1출력권선(2)으로 용량성 결합을 거의 생성하지 않는다. 상쇄권선(44)의 시작점이 연결되는 제2결합부(43-2)의 전체 면적의 평균 전위는 상쇄권선(44)의 전체 면적의 평균 전위의 2 배이다. 그러므로, 제1결합부(43-1)와 제2결합부(43-2)는 상쇄권선(44)이 제1출력권선(2)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 최대 2배 크기의 스위칭 주파수 성분의 용량성 결합을 제1출력권선(2)으로 생성한다. 제1결합부(43-1)와 제2결합부(43-2)와 상쇄권선(44)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 합의 크기가 도 3의 종래기술의 제2상쇄권선(11)이 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 크기와 같다면, 상쇄권선(44)이 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 크기를 도 3의 종래기술의 제2상쇄권선(11)이 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 크기의 1/3이 된다. 그러므로, 상쇄권선(44)의 턴 수는 약 7턴으로 감소할 수 있다. 그런데, 상쇄권선(44)의 턴 수가 도 3의 종래기술의 제2상쇄권선(11)의 11 턴보다 작은 7턴으로 감소하면, 상쇄권선(44)을 구성하는 도체 사이의 간격의 개수도 도 3의 종래기술의 제2상쇄권선(11)의 10개의 간격에서 6개의 간격으로 감소하므로, 끝 층의 PCB면에서 도체가 없는 빈 면(43-6)의 면적이 40%나 감소한다. 그래서, 빈 면(43-6)을 통해서 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제2출력권선(4)으로 생성하는 용량성 결합도 40% 감소한다. 따라서, 상쇄권선(44)의 턴 수는 7턴 보다도 더 작게 줄일 수 있고, 그로 인해, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제2출력권선(4)으로 생성하는 용량성 결합의 크기는 더욱 감소한다.The first coupling part 43-1 having the electric ground potential of the primary side of the power supply device is a capacitive coupling of the switching frequency components generated from the first input winding 25 to the first output winding 2-1. The capacitive coupling of the switching frequency components of the same polarity as is generated by the first output winding 2-1. The second coupling portion 43-2 to which the potential of the starting point of the offset winding 44 is connected is opposite to the capacitive coupling of the switching frequency components generated from the first input winding 25 to the first output winding 2-1. Capacitive coupling of the switching frequency components of the polarity is generated by the first output winding 2-1. However, by blocking the first coupling part 43-1 and the second coupling part 43-2, the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9 are output as the first. Almost no capacitive coupling is created with the winding (2). The average potential of the total area of the second coupling portion 43-2 to which the start point of the offset winding 44 is connected is twice the average potential of the total area of the offset winding 44. Therefore, the first coupling portion 43-1 and the second coupling portion 43-2 have a maximum size of twice the capacitive coupling of the switching frequency components generated by the offset winding 44 as the first output winding 2 The capacitive coupling of the switching frequency components of is produced by the first output winding (2). Capacitiveness of the switching frequency component generated by the first and second coupling parts 43-1 and 43-2 and the offset winding 44 as the first and second output windings 2 and 4 If the size of the sum of the couplings is the same as the size of the capacitive coupling of the switching frequency components generated by the second offset winding 11 of the prior art in FIG. 3 as the second output winding 4, the offset winding 44 is the second The magnitude of the capacitive coupling of the switching frequency components generated by the output winding 4 is the capacitive coupling of the switching frequency components generated by the second offset winding 11 of the prior art in FIG. It becomes 1/3 of the size. Therefore, the number of turns of the offset winding 44 can be reduced to about 7 turns. By the way, if the number of turns of the offset winding 44 is reduced to 7 turns, which is less than 11 turns of the second offset winding 11 of FIG. 3, the number of gaps between the conductors constituting the offset winding 44 is also shown. Since it is reduced by 6 intervals from 10 intervals of the second offset winding 11 of the prior art of 3, the area of the empty surface 43-6 without a conductor in the PCB surface of the end layer is reduced by 40%. Therefore, the capacitive coupling generated by the input winding (7), the first auxiliary winding (8) and the second auxiliary winding (9) to the second output winding (4) through the blank surface (43-6) is also reduced by 40%. do. Therefore, the number of turns of the offset winding 44 can be reduced to be smaller than that of 7 turns, and thus, the input winding 7 and the first auxiliary winding 8 and the second auxiliary winding 9 are converted to the second output winding ( The size of capacitive bonds produced by 4) is further reduced.
도 22의 다층PCB부(3-17)를 사용하는 도 2의 전원 장치는, 첫째 층의 PCB면에서 제1결합부(43-1)가 차지하는 면적의 비율과 제2결합부(43-2)가 차지하는 면적의 비율을 조절하거나, 상쇄권선(44)의 턴 수 혹은 상쇄권선(44)을 구성하는 도체의 면적을 조절하여, 전원 장치의 1차측의 모든 요소들이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 스위칭 주파수 성분의 용량성 결합의 합을 “영”에 근접시키며, 전원장치의 출력선로의 스위칭 주파수 성분의 noise를 아주 낮게 낮춘다.In the power supply device of FIG. 2 using the multilayer PCB portion 3-17 of FIG. 22, the ratio of the area occupied by the first coupling portion 43-1 on the first-layer PCB surface and the second coupling portion 43-2 ), by adjusting the ratio of the area occupied by the offset winding 44, or by adjusting the number of turns of the offset winding 44 or the area of the conductor constituting the offset winding 44, all elements on the primary side of the power supply device are converted to the first output winding (2) The sum of the capacitive coupling of the switching frequency components generated by the and the second output winding 4 is close to "zero", and the noise of the switching frequency component of the output line of the power supply is very low.
도 22의 다층PCB부(3-17)가 비록 10층의 PCB면에 의해 구성되지만, 도 22의 다층PCB부(3-17)를 사용하는 도 2의 전원 장치에서, 입력권선(7)과 제1보조권선(8)과 제2보조권선(9)이 제1출력권선(2)과 제2출력권선(4)으로 생성하는 용량성 결합의 크기가 도 3의 다층PCB부(3)에 비해 훨씬 작으므로, 제1결합부(43-1)와 제2결합부(43-2)와 제3결합부(45)가 생성하는 역 극성의 용량성 결합에 의해서 상쇄가 이루어진 후의 용량성 결합의 잔량도 도 3의 다층PCB부(3)에 비해 훨씬 감소하고, 종래기술에 비해 외부로 스위칭 주파수 성분과 고주파 성분의 노이즈의 영향을 훨씬 작게 미치게 되는 장점을 가진다.Although the multilayer PCB section 3-17 of Fig. 22 is composed of a 10-layer PCB surface, in the power supply device of Fig. 2 using the multilayer PCB unit 3-17 of Fig. 22, the input winding 7 and the The size of the capacitive coupling created by the first auxiliary winding 8 and the second auxiliary winding 9 to the first output winding 2 and the second output winding 4 is in the multilayer PCB unit 3 of FIG. Since it is much smaller than that, the capacitive coupling after cancellation is achieved by the reverse polarity capacitive coupling generated by the first coupling portion 43-1, the second coupling portion 43-2, and the third coupling portion 45. The residual amount of is also significantly reduced compared to the multilayer PCB unit 3 of FIG. 3, and has an advantage that the influence of noise of the switching frequency component and the high-frequency component to the outside is much smaller than that of the prior art.
