“…Then, the entire system is solved via the harmonic coupling matrix equation to account for the interaction between the converter dc system and the ac terminal voltage. In (4.6), Iac and Vac can be expanded to include both positive and negative sequence components, and Idc can be expanded to include the firing angle controls [13]. The harmonic coupling matrix provides a relationship between the harmonic components of ac side voltage/ current and the dc side voltage/current of the converter.…”

Abstract-The harmonic currents generated by the single-phase rectifier are well known. As the levels of these currents become larger, the use of power conditioners such as shunt active filters to lower the levels is becoming more attractive. In order to analyze the interaction between the condition, ac system, and rectifier it is necessary to have an accurate model of the rectifier. This paper describes a frequency-domain analytical model of the single-phase rectifier. The model includes the dominant frequency transfer mechanisms. These are the direct transfer and that due to the modulation of the switching instants. A small-signal linearized analysis is presented and the behavior predicted is confirmed by perturbation analysis using time-domain simulation. Accurate results are obtained, and the importance of including the switching instant modulation is shown.Index Terms-Frequency-domain analysis, harmonic analysis, power quality, rectifier.

“…[1] presents a transfer function model based on the modulation theory that uses two transfer functions to relate the dc and ac sides of the converter. In [2]- [4], the authors propose efficient techniques by linearizing the interaction between the converter dc system and the ac network at different converter operating points of interests.…”

Original scientific paperThis paper proposes a simplified equivalent circuit model that can be used in the presentation of characteristic harmonic components generated by full wave diode rectifiers. In the model, the load current is assumed to be constant as in many industrial applications. In order to obtain an accurate and exact analysis, the proposed model involves both current harmonics on AC side and voltage harmonics on DC side of the full wave rectifiers. The model depends on Fourier series expansion for the load voltage and the source current waveforms.

U radu je predložen pojednostavljeni ekvivalentni model električnog kruga koji se može koristiti za prikaz karakterističnih harmoničkih komponenata koje generira punovalni ispravljač. Pretpostavka modela je konstantan iznos struje tereta, što ječesti slučaj u industrijskim primjenama. Kako bi se postigla vjerodostojnost modela, predloženi model uključuje harmonike struje na AC strani kao i harmonike napone na DC strani punovalnog ispravljača. Model ovisi o razvoju Fourierovog reda za valne oblike napona tereta i struje izvora Ključne riječi: harmonički model, ekvivalentni električni krug, punovalni ispravljač
