Widespread applications of power electronic-based loads continue to increase concerns over harmonic distortion. However, it is desired to draw purely sinusoidal current from the distribution network, but this is no longer the case with new generation loads, consisting of power electronic converters. The current harmonics produced by these non-linear loads further result in voltage distortion and leads...
This paper presents a detailed study on the effect of power system voltage unbalance on the harmonics injected by a ac-dc rectifier load. This study gives an insight about the role of sequence voltage components in voltage unbalance analysis. The simulations are carried out in time domain and the frequency spectra of the distorted waveform (input and output) are obtained using fast Fourier transform...
