The paper discusses the influence of a dead time duration on the input current spectrum of voltage-source active rectifiers. The main body shows the simulations of a three-phase voltage-source active rectifier with respects to the dead times. This section especially describes the figures which present the harmonics analysis of the input current and its dependence on the dead time duration. The last...
This paper deals with analysis of the current drawn from the grid by the voltage-source active rectifier. These converters are designed and controlled so that the current drawn from the grid approaches sine wave and power factor approaches one. Analytical calculations of harmonic analysis of this current based on the Fourier series are performed on a simplified model. These analytical calculations...
Voltage-source active rectifier eliminates characteristics harmonics, which are drawn by diode (thyristor) rectifiers from the electrical grid. The paper shows analytical analysis of the current drawn from the grid by voltage-source active rectifier. The first part presents the principle of the voltage-source active rectifier. The next part describes both analyses of the current and the last part...
