Analysis of the Effect of Interference in the Power Distribution System of the Current Converter Control Board on the Operation of the Power Supply of the Air Conditioning System on the ISS

Annotation The purpose of this work is to improve the electromagnetic compatibility in the current transformer of the converter, thereby increasing the stability of its operation by means of interference suppression techniques in the power supply system of the control board and, as a result, its modernization. The object of the study is the converter of the current of the BC SCR on the ISS. The subject of the study, are noise suppression techniques. This graduation qualification work consists of five parts. The first part presents the requirements for electromagnetic compatibility on the ISS.In the second part of the final qualifying work, the design and layout of the current transformer is considered. The design of the converter control board for the current converter of the SCS is described in detail, since in this work the power distribution system of the control board of the instrument is analyzed. The third part of the work is the analysis of the interference of the current converter of the converter. Measurements of the level of interference with the oscilloscope and analysis of the received oscillograms are carried out. The fourth part deals with theoretical information about the power distribution system in printed circuit boards, describes the effect of interference on the device as a whole, and methods for solving interference suppression. The recommendations on the improvement of the control board for the current converter of the converter are presented. The fifth part describes the upgraded control board and measures the level of interference in the converter of the AC current. In conclusion, conclusions on the work performed are presented.
