Improvement of electromagnetic compatibility in power converters of electric rolling stock

Abstract

The sources of distortion of the quality of electrical energy are both a large number of household impulse consumers of electricity, and single powerful impulse nonlinear consumers, such as traction substations of railways and subways, frequency converters of electric drives, the growing number of electric vehicle charging stations, etc. Electric drives with DC motors powered by an AC electrical network are quite widespread, both in industry and in railway transport. Its rectifiers are an important component of AC electrical rolling stock. The power factor, the level of emission higher harmonics of currents and reactive power, as well as the possibility of realizing the mode of recuperation of electric rolling stock depend on traction rectifiers.
