Modelling and Simulation of an Electric Transport High-Power Three-Phase Full-Wave Uncontrolled Rectifier in the MATLAB/Simulink Environment

A three-phase full-wave high-power uncontrolled rectifier of a power substation of electric trolleybus transport system has been modelled and simulated in the programming environment of MATLAB/Simulink. The obtained simulation results are analysed and they confirmed the mathematical descriptions of the electrical processes and semiconductor device principles. The shapes of the currents and voltages are analysed and solution guidelines are given to reduce the non-sinusoidal distortions of the currents. The developed model can find application in the modelling and studying of the operating and emergency modes of rectifiers as electronic converters of the industrial, renewable energy systems, etc.
