Analýza harmonického spektra a deformačního výkonu neřízených usměrňovačů s kapacitní zátěží

Abstract

This bachelor's thesis is devoted to the impact of rectifiers on the power grid. The work primarily focuses on uncontrolled rectifiers with a capacitive load and the analysis of the influence of this load on the waveforms and frequency spectrum of the input current. For analysis purposes, models of these rectifiers were created in OrCAD Capture, and simulations were subsequently performed. The results of the simulations show the effect of the capacitive load on the power supply network and, at the same time, serve to determine the applicability of uncontrolled rectifiers with a capacitive load in practice with regard to the requirements of standards for maintaining electromagnetic compatibility and, therefore, their operation in the public distribution network.
