An analysis and a simulation of static frequency converter using three-phase rectifiers with almost sinusoidal input currents

In this paper, an analysis and a simulation of the frequency converter with the three-phase low-harmonic rectifier equipped with inductors, capacitors and diodes is presented. Inductors and capacitors are used in conjunction with the three-phase diode rectifier bridge to improve the waveform of the current drawn from the utility grid. The functioning stages are established and, on this basis, design considerations are commented. The converter characteristics are determined as function of the load current.
