Analysis of topologies of active four-quadrant rectifiers for implementing the Industry 4.0 principles in traffic power supply systems
Industry 4.0, Vol. 4 (2019), Issue 3, pg(s) 106-109
Implementation of the principles of “INDUSTRY 4.0” into the traction power supply systems implies the introduction of power factor correction modes and the possibility of bi-directional energy transfer in the DC traction substations used on railways and subways. The article provides an overview and comparison of active rectifier circuits, which allow to realize power factor correction and eliminate the higher harmonics of the input current. A number of requirements are presented, on the basis of which the optimal scheme for the rectifier of the traction substation was chosen.
