“…To meet the regulatory requirements IEEE519 [1] and IEC100032 [2], an active power factor correction (PFC) converter is normally added between the line and the load to attenuate the input current harmonics. The commonly used PFC converters employ a two‐stage configuration including a boost PFC stage and a cascaded DC/DC stage [3–5].…”

A double-ended forward converter with an input inductor–capacitor filter has inherent power factor correction\ud (PFC) properties and continuous input current when operating in discontinuous-capacitor-voltage mode (DCVM). In this\ud study, the minimum separable switching configuration modelling is applied to the proposed converter operating in\ud DCVM to obtain a small-signal model of the converter. The impact of the circuit parameters on the small-signal\ud characteristic are discussed in details. The difference between the small-signal behaviour of the converter when\ud operating as a DC/DC converter and a PFC converter is investigated. The modelling methodology is intended for the\ud design of controllers in closed-loop operation. A 100 W prototype is implemented to demonstrate the feature of the\ud small-signal behaviour

“…The international standards such as IEC61000‐3‐2 [1] and IEEE 519 [2] require that the harmonic content of the ac input current is below certain limits. In an effort to comply with the standards, considerable efforts have been made on the development of the power factor correction (PFC) converter topologies.…”

A double-ended forward converter with an input inductor-capacitor (LC) filter operating in discontinuous capacitor voltage mode is proposed in this study. The most important advantage of the proposed topology is that the operations of the proposed converter make the switches bear only a portion of the peak capacitor voltage without any extra control and auxiliary winding, which result in a relatively low switches voltage stress. This study presents a detailed analysis of the switch voltage stress. The experimental results for a 36 V dc /100 W are presented.

“…These devices are likely to introduce significant harmonic pollution into the power system, which may result in equipment malfunction and premature equipment failure, communication interference, or even the malfunction of protective devices. In addition, the harmonic distortion limits are being enforced by the utility grid, and so large industrial facilities whose loads are primarily rectifiers face severe penalties due to their poor power factors [1][2][3][4][5]. Thus, harmonic suppression and reactive power support are becoming important subjects among electric power engineers these days.…”

Many conventional methods focus on reducing the harmful impact of the poor power quality in industrial rectifier systems, but they focus more on the harmonic problems of the utility grid than they do on that of the rectifier transformer; hence, the rectifier transformer would still be adversely affected by harmonic pollution. In order to solve the problem, a filtering rectifier transformer is proposed that adopts a harmonic current drainage system that incorporates tertiary winding and tuned harmonic filters. The impedance of the tertiary winding is specially designed and the tuned harmonic filters work together to restrain the harmonic current and give a good performance in the reactive power compensation close to the harmonic source. By deducing the current relationships between the windings of the filtering rectifier transformer, the principles of the harmonic suppression and reactive compensation are elaborated.The theoretical analysis shows that if the harmonic current drainage system is out of service, the characteristics of the operation parameters of the filtering rectifier transformer are the same as those of the conventional one. While it is in service, the filtering rectifier transformer could improve the total harmonic distortion of the grid side current, decrease the grid side current, reduce the grid side power, and enhance the grid side power factor. A prototype filtering rectifier transformer was built and installed in an aluminum smelting plant. Both the simulation and the field measurement results verify the correctness of the theoretical analysis. The mathematical relationships deduced in the paper will contribute to further study of the filtering rectifier transformer on the vibration and temperature rise suppression of the windings. The project has demonstrated that the proposed filtering rectifier transformer has promising prospects in various industrial power applications.
