碩士 === 淡江大學 === 資訊工程學系 === 90 === With the fast development of power electronic techniques, the switch-mode power supplies have been widely employed in the electrical products for industrial and commercial applications. These high-frequency switching power supplies are inherently noise sources and can affect the operation of the other equipments. Therefore, it is very important to investigate and study the electromagnetic interference problems. In this thesis, a PC-based automatic measurement and filter design system for the electromagnetic interference emission is developed. The effort of solving the conductive EMI is greatly reduced by the fast computing speed and the friendly man-machine interface of the PC. The noise measurement and suppression procedure established can accomplish the reduction of the developing period and cost. Not only the production is speeded up, but also the acceptability of the product to the publicans can increase.
