چکیده: Abstract: Nowadays, the use of switching mode power supplies as a power supply in electronic devices has become very widespread, and the reason is the advantages of switching mode power supplies over linear power supplies, including low volume of the power ratio, acceptable reliability, the possibility of isolating at inputs and outputs, and high efficiency over linear power supplies. The most important disadvantage of these sources compared to their linear competitor is the production of electromagnetic radiation, and the various methods have been proposed to reduce this radiation. In the first chapter, the research work done on the subject of this thesis is reviewed and the types of electromagnetic interference, features and differences of each of them are examined. In the second chapter, a number of sample boards have been designed and made manually using Altium Designer software. Then, using different measurement methods, and the measurement results are compared with the simulation results by CST software. Finally, in the third chapter, the flyback converter circuit is designed by AltiumDesigner software, circuit simulation using CST software, and the necessary changes have been made in the design and as a result the reduction of electromagnetic radiation has been discussed
