Investigation of Analog And Spase-Vector Pulse-Width Modulation In Three-Phase Current-Source Rectifiers

The article presents a investigation of three-phase current-source rectifiers. Special analog sinusoidal pulse-width modulation algorithms with phas-shift compensation for three-phase current-source rectifier has been proposed. In the Matlab/Simulink program, a model of an current-source rectifier was developed. The processes of rectification and recuperation when applying the proposed modulation algorithm were studied. The features of the spectrum of higher harmonics of the input current are determined. It is shown that in the rectification and energy generation modes in the three-phase network, the current source rectifier implements a sinusoidal current form with a power factor greater than 0.99.
