EMC Evaluation of High-power Electronic System Based on Improved AHP-TOPSIS

The electronic system is equipped with a large number of electronic and electrical equipment, which forms a complex electromagnetic field environment both internally and externally. This will lead to performance degradation or equipment failure when electronic and electrical equipment work together. Therefore, electromagnetic compatibility assessment plays an important role in the design and normal operation of electronic systems. This article analyzes the shortcomings and scope of existing electromagnetic compatibility evaluation methods, and on this basis, an improved AHP-TOPSIS evaluation method is used to evaluate the electromagnetic compatibility of high-power electronic systems. Firstly, the AHP-TOPSIS algorithm needs to establish an electromagnetic compatibility evaluation index system. Use software simulation and actual testing methods to obtain indicator data, and compare the indicator data with standard values to ensure the correctness and rationality of the indicator data. Subsequently, by solving the judgment matrix, the Analytic Hierarchy Process (AHP) algorithm can calculate the weight of each sub indicator. And the calculation results of the AHP algorithm are substituted into the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) algorithm. Finally, calculate the electromagnetic compatibility performance of each scheme. The improved AHPTOPSIS algorithm can effectively reduce errors caused by subjective human factors and objective factors in theoretical data. This article verifies the correctness of the improved AHP-TOPSIS algorithm by evaluating the electromagnetic compatibility of a high-power electronic system. This article uses the improved AHP-TOPSIS evaluation algorithm to evaluate and compare the electromagnetic compatibility of system design schemes, and ultimately calculates the optimal electromagnetic compatibility performance. The calculation results validate the effectiveness of this method and can provide assistance for the rectification and design of high-power electronic systems.
