Dual Boost High performances Power Factor Correction (PFC)
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008In this paper a novel power factor correction (PFC) dual boost scheme is proposed. It is based on an optimized power sharing where the active filtering approach is used to increase the current quality and at the same time to reduce the switching losses.

Techniques to obtain single-stage power supplies with power factor correction (PFC)
International Journal of Electronics, 2011In order to comply with the standards, the input current of the switch mode power supplies (SMPS) must be almost sinusoidal, i.e. the SMPS must achieve power factor correction. This requirement is normally reached with the use of an additional input converter, typically a boost, resulting in a two-stage SMPS with the inherent drawbacks: high cost and ...

A new power factor correction technique using PFC boost converter
2012 11th International Conference on Environment and Electrical Engineering, 2012Generally non-linear loads are the main source of harmonics. This paper presents one new control scheme to compensate the harmonic current generated by the diode rectifier so as to achieve a power factor nearer to unity and regulate the DC-bus voltage.

Analysis of single-phase boost power factor correction (PFC) converter
Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999In this paper, the single-phase boost power factor correction converter is discussed in detail. With the Fourier series analysis of the general model, the low frequency model and high frequency model are proposed. From the low frequency model, the expression of the duty cycle, the boundary between continuous current mode (CCM) and discontinuous current

DSP implementation of predictive control strategy for power factor correction (PFC)
Nineteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2004. APEC '04., 2004A predictive algorithm for digital control PFC is presented in this paper. Based on this algorithm, all of the duty cycles required to achieve unity power factor in one half line period are calculated in advance by the DSP. A boost converter controlled by these precalculated duty cycles can achieve sinusoidal current waveform.

A DSP based controller for power factor correction (PFC) in a rectifier circuit
APEC 2001. Sixteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.01CH37181), 2002In this paper a digital signal processor (DSP) based power factor correction (PFC) scheme is presented. A dual-loop controller is designed to control the average input AC current as well as DC bus voltage. The DSP controller is implemented and tested. Design methodologies and trade-offs such as discrete-time implementation methods are also presented.

Operation of three-phase power factor corrected (PFC) rectifiers
International Aegean Conference on Electrical Machines and Power Electronics and Electromotion, Joint Conference, 2011Rectifier circuits make a large number of higher harmonics in the mains and lower the power factor (PF). To reduce this harmful effect, rectifier circuits with electronic control are introduced. This article presents two Power Factor Correction rectifier circuits: 1- and 3-phase circuits. We present here the method of controlling these rectifiers, that

Abstract Low voltage electrical power distribution systems within buildings and railway systems use alternating current (AC). The voltage and current within these AC systems commonly have an inherent phase difference in their time-based waveforms due to capacitance and inductance of the loads, cables and supply systems involved in the
