Abstract

This paper presents the optimal design of flyback transformer with the flat copper winding method of injection type suitable for the small-size and winding method of automatic type used in 90W DC to DC converter for LED-TV. This paper also proposes the flyback transformer with the flat copper winding method of injection type capable of the winding method of automatic type and the reduction of transformer size and enhanced uniformity in electrical characteristics compared to the conventional mass-production flyback transformer with the winding method of manual type. In particular, the flat copper winding transformer of injection type proposed in this paper is constructed in a vertical winding method of its transformer to realize the winding method of automatic type. The primary and secondary windings of flyback transformer with the flat copper winding method of injection type used the conventional winding, triple insulated winding and the flat copper winding method of injection type, respectively. The optimal design of flyback transformer with the flat copper winding transformer of injection type proposed in this paper suitable for small-size and winding method of automatic type was carried out based on the simulation results using Maxwell 2D and 3D tool.

본 논문에서는 90W급 LED-TV용 DC-DC Flyback 컨버터에 사용되고 있는 소형화 및 권선 자동화에 적합한 사출형 평면 동판 권선 방식의 Flyback 변압기 최적화 설계에 대해서 나타낸다. 또한 본 논문에서는 수동권선방식의 기존 양산 Flyback 변압기에 비해 권선 자동화, Trans 체적 저감 및 전기적 특성 동질성 향상이 가능한 사출형 평면 동판 권선 방식의 Flyback 변압기를 제안한다. 특히 본 논문에서 제안한 사출형 평면 동판 권선 변압기는 권선 자동화를 위하여 수직형 권선 방식으로 구성한다. 본 논문 제안한 사출형 평면 동판 권선 방식의 Flyback 변압기의 1차측과 2차측 권선은 각각 기존 권선, 3중 절연 권선 및 사출형 평면 동판권선을 사용하였다. 최종적으로 Maxwell 2D 및 3D Tool을 이용한 시뮬레이션 결과를 토대로 본 논문에서 제안한 소형화 및 권선 자동화에 적합한 사출형 평면 동판 권선 방식의 Flyback 변압기 최적화 설계를 수행하였다.
