본 논문에서는 단일 스위치 방식의 포워드컨버터에서 스위칭소자에 직류버스전압의 합, 트랜스포머전압의 반영, 그리고 턴오프 누설 인덕턴스의 스파이크와 같은 스트레스가 가해지므로 이중 스위치 방식의 포워드 컨버터를 설계 및 제작하여 출력특성을 고찰하였다. 제어용 IC는 PFC와 PWM 제어가 하나의 칩에서 이루어 지는 TI사의 UCC28510을 이용하여 21V 및 13.5V의 다중출력 포워드 컨버터 SMPS를 설계 구성하였다.

Bill of material (BOM), which structurally represents the relation among parts constructing a product, is usually created when enterprises start to develop a new product. And it is shown as various types of BOM according to business needs and usage such as eBOM(engineering BOM), gBOM(green BOM), mBOM(manufacturing BOM), pBOM(process BOM), etc. eBOM, generally called BOM and created in the design stage of the new product, includes the drawing information of parts in the view of product function. eBOM is extended to gBOM adding the material information of parts to cope with international regulations for environment. eBOM is transformed to mBOM, which includes manufacturing sequence of parts and adds some parts required to fabricate parts and to assemble the product. mBOM is also extended to pBOM adding the process information of each part and additional assembly processes. This study introduces the concept of multi-BOM covering eBOM, gBOM, mBOM and pBOM, and proposes an advanced way to manage product data using multi-BOM system. The multi-BOM system proposed is to manage their relations using transformation function of BOM and master information of all BOMs.

Manufacturing enterprises have faced a strong pressure to obey the complex regulation related to product, which are getting more complicated. Their management activities have been also restricted by these regulations such as the ban on importing and marketing of products including dangerous materials, the regulation of carbon gas emission, and so on. In these trends, most makers of end products and components are already aware of the seriousness or importance of this situation because they have the final responsibility of product liability. However, small and medium enterprises (SMEs) have confronted the difficulty to cope with the regulations using poor systems comparing to global enterprises. As a tool to support SMEs, this study proposes the green BOM system which deals with the world"s environmental regulations by managing components’ material based on bill-ofmaterial (BOM) systematically. The green BOM system was designed to cope with the EU regulations such as RoHS and WEEE, the bases of environmental regulations. SMEs can manage technical documents of material such as the material inspection sheet, certification, and the material master to be the standard of material control and also supervise the material properties, ingredients, and recycling ratios of end products/components. The green BOM system also provides SMEs with the powerful material report which shows the validity of end products/components to obey the regulations. One of its strong merits is to share these information with customers and suppliers directly and synchronously.
