Abstract

The structure of a power subsystem with the network lowering transformer and the active rectifier, providing a bilateral exchange of energy between a power line and electric machine for low-voltage direct current electric drive is considered. In MATLAB/Simulink package with application of SimPowerSystems appendix, the model of the closed-loop system of the direct current electric drive with the active rectifier on the basis of low-voltage machine PBV-100M is developed. Modeling is executed and its results are analyzed.


Keywords: active rectifier, closed-loop system of the subordinated regulation, pulse-width converter, direct current electric drive, recuperation energy.
