Software implement of EMC analysis and design for electric system

In this paper, a software implementation of EMC analysis and design for electric systems is discussed. In a common sense, the EMC analysis uses s stepwise-filtering method, which can be split into two parts: the computing part and the management part. Using computer software the managing can be implemented part in common appearance; the computing part can be modified based on factual instance. An EMC analysis and design software for a large electric system was achieved successfully by using these techniques.
