- W4385641789 abstract "The article deals with the study of parameters of power supply control systems for the position of non-disassembly vibroacoustic diagnostics of rotary units of rolling stock. It is assumed that the power sources transmit constant electricity to bring the traction motors of electric locomotives and electric trains into rotation with the required frequency at the position of non-disassembly diagnostics of bearings. Experiments were performed following the MatLab/Simulink software. Analytical methods are used to determine the parameters of traction motors of electric rolling stock according to the program and the parameters of the controlled part as the power factor of various power supply options. The energy indicators of electric traction motors of electric rolling stock were determined in tabular and analytical forms, controlled parameters with different power coefficients of power sources. Based on the assessment of the energy indicators of various power supply options, it is concluded that it is advisable to use a circuit with a pulse converter in the position of vibroacoustic diagnostics of rotary assemblies. A variant of an energy–efficient power supply for non-disassembled vibroacoustic diagnostics is proposed, including an uncontrolled semiconductor rectifier and a pulse converter executed on an IGBT transistor. A radical way to increase the power factor of the power supply is using pulse voltage regulation." @default.
