Modelación y simulación de un conversor estático para alimentar cargas monofásicas desde un sistema de alimentación de modo balanceado.

Abstract

Feeding a single-phase load with a threephase network generates current and voltage imbalances in the system, degrading the utility generator, specially its mechanical system. A review of the state of the art shows a renewed interest in exploring strategies that allow feeding single-phase loads from three-phase circuits. All of them involve the use of power electronics. This paper studies an entirely different approach with a different configuration to load a single-phase generator, keeping its voltages and currents balanced. There is a complete description of its operating principle. A model is proposed and simulated in Simulink. Results of the waveforms are shown and discussed, as well as possible disadvantages of the topology, when loading with resistive and lagging power factor impedances. Finally, a brief list of future works in this line of research and its relationship with other publications are presented.
