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 of the simplified model are compared with simulations. It is proved that even when the simplified model is used; the results of the analytical calculations differ very little from simulations. Little effect of active rectifier load on the absolute values of the current harmonics is proved in this paper. Absence of characteristic harmonics produced by diode rectifier in the spectrum of the current and the effect of the switching frequency for the presence of new harmonic current are shown in simulations.Index Terms--voltage-source active rectifier, current harmonics, Fourier transform, harmonic analysis, total harmonic distortion UAO, UBO, uco [V]: Uaf, Ubf, Ucf [V]: u., Ub, Uc [V]: Uam(l) [V]: Uafm(l) [V]: i., ib, ic [A]: lam(l) [A]: iz [A]: I ZN [A]: fsw [Hz]: s:

“…Voltage-source active rectifiers have many advantages; they draw current with low distortion and with high power factor that is presented in publications [17]- [18]. Voltage-source active rectifiers can compensate the short-term voltage drops within a certain range, if they are applied to frequency converters.…”

The paper presents the possibilities of the use of voltage-source active rectifiers to minimize the effect of voltage drops on the DC link voltage magnitude of frequency converters. The control of voltage-source active rectifiers can compensate the short-term voltage drops within a certain range. The paper describes principle of the operating of voltage-source active rectifiers and the range of the voltage drops that can be compensated. The paper points out that it is important to observe the load current and the DC link voltage of converters.
