Gurin V. Improving the effectiveness of noise reduction means in power supply systems with high-frequency transistor converters.

The object of research: transistor converters of key type as electromagnetic interference generators. The purpose of research: to improve the efficiency of means of ensuring electromagnetic compatibility in power supply systems with high-frequency transistor converters through the development and implementation of new circuit design and design methods for their construction. Method of research: the methods of the theory of electrical circuits were used in the work. Confirmation of the reliability of theoretical studies results provided by using the software package OrCAD-PSpice and natural experiment. Theoretical and practical results and innovations: based on theoretical studies, an urgent problem has been solved to improve the efficiency of methods for ensuring electromagnetic compatibility in power supply systems with high-frequency transistor converters. Developed new circuit design and constructive methods for building noise reduction means, which allowed to reduce the cost, and weight and size parameters of transistor converters. A subject degree of introduction: the main results of the work were introduced in the EMSBI Ltd. The scientific results were used in the scientific process of the Department of Industrial Electronics at them NTUU "KPI. Igor Sikorsky. Efficiency of implementation: a significant technical and economical effect has been obtained, which is to increase the electromagnetic compatibility in power supply systems with high-frequency transistor electric power converters (decrease in mass-dimensional parameters of transistor converters, decrease in the price of transistor converter and increase its electrical safety). Area of use: semiconductor power converters.
