Performance Evaluation of PFC Boost Converters

IJIREEICE, 2015

The use of electronic equipment has increased in last few years. Therefore there is an immense need to ensure that the line current harmonics of any equipment connected to AC main line is limited to comply the regulatory standard. This requirement is satisfied by introducing some form of Power factor Correction (PFC) techniques to make the input current sinusoidal and reduce the harmonics. In this paper, a systematic review of power factor correction (PFC) boost rectifiers is presented. Performance comparison of conventional PFC boost rectifier at different duty ratio and voltages are shown and their efficiency is calculated.

Comprehensive Design and Optimization of a High-Power-Density Single-Phase Boost PFC

IEEE Transactions on Industrial Electronics, 2009

The design of a single-phase boost power-factorcorrection (PFC) circuit is associated with a large variety of considerations, such as the following questions. Which operation mode should be selected (e.g., continuous or discontinuous operation)? How many interleaved boost cells are advantageous? Which switching frequency should be selected? What is the optimum number of EMI input filter stages? Which semiconductor technology should be chosen? All these issues have a significant influence on the converter efficiency and power density. In this paper, the aforementioned questions are addressed for exemplary specifications of the PFC (300-W output power, 400-V output voltage, and 230-V mains voltage), whereby the focus in the design is mainly put on very high power density. As a result, different design points are identified and comparatively evaluated. By considering different aspects such as volume, losses, capacitor lifetime, and also cost issues (e.g., by additional current sensors or expensive silicon carbide devices), a dual-interleaved PFC operated in discontinuous conduction mode at 200 kHz is selected. With an experimental prototype, a superior power density of 5.5 kW/L and a system efficiency of 96.4% are achieved, which is close to the values predicted by the design procedure. Furthermore, measurements verify a near-unity power factor (PF = 99.7%) and the compliance with electromagnetic compatibility conducted noise emission standards. Finally, it is investigated to which extent the power density could be further increased by an integration of the input filter in the PCB.

A Review on Quadratic Boost Topology-Based PFC Techniques

International Journal of Emerging Trends in Engineering Research, 2021

Electronic devices require DC voltage for their operation so rectification (AC to DC conversion) is needed to convert AC voltage from the mains to DC. During this conversion, harmonics are generated in the system as well as power factor (PF) gets poor hence degrading power quality. Power factor correction (PFC) converters are being commonly used to increase PF and reduce harmonics. Boost PFC Converter is the mostly used topology for active power factor correction because of several benefits like series input inductor, high PF, but its voltage gain is not that good and it has output voltage ripple. Quadratic Boost PFC Converter can be used to overcome these two drawbacks by providing high voltage gain and less output voltage ripples. This paper represents applications and topologies of Quadratic Boost Converter, latest control techniques to achieve high voltage gain, regulated output and, high PF. Also, comparison is made between Boost Converter and Quadratic Boost PFC Converter. Finally, conclusion is made of this survey.

Comprehensive review of high power factor ac-dc boost converters for PFC applications

International Journal of Electronics, 2014

High power factor rectifiers have been consolidated as an effective solution to improve power quality indices in terms of input power factor correction, reduction in the total harmonic distortion of the input current and also regulated dc voltages. Within this context, this subject has motivated the introduction of numerous converter topologies based on classic dc-dc structures associated with novel control techniques, thus leading to the manufacturing of dedicated integrated circuits that allow high input power factor by adding a front-end stage to switch-mode converters. In particular, boost converters in continuous current mode (CCM) are widely employed since they allow obtaining minimised electromagnetic interference levels. This work is concerned with a literature review involving relevant ac-dc single-phase boost-based topologies with high input power factor. The evolution of aspects regarding the conventional boost converter is shown in terms of improved characteristics inherent to other ac-dc boost converters. Additionally, the work intends to be a fast and concise reference to single-phase ac-dc boost converters operating in CCM for engineers, researchers and experts in the field of power electronics by properly analysing and comparing the aforementioned rectifiers.

Design and Simulation of PFC Circuit for AC/DC Converter Based on PWM Boost Regulator

In this paper a simple power factor correction PFC circuit was designed, simulated and tested for AC/DC converter which generates input current harmonics due to its non-linear characteristics. PFC was achieved through current harmonics mitigation by using PWM boost regulator. The circuit utilizes the charging and disc arching increments of boost inductor current to shape a sinusoidal input current. Inductor current was controlled by means of PWM controller. The controller accepts two feed back signals, the first is the inductor current and the other is the output voltage of the AC/DC converter. The simulation results of fast fourier transform FFT show a grate reduction in current harmonic which in turns tends to a grate improvement in power factor.

Computer Applications in Engineering Education, 2009

The aim of this work is to introduce the power quality phenomenon to electrical engineering students by modeling and simulation of boost type power factor correction (PFC) circuits. In the study, after introducing the importance of the power factor, the methods of improving power factor and the topologies used for single-phase acÀdc boost PFC are discussed. Then, single-phase boost type PFC converters are analyzed and simulated via Simplorer 6.0 component-level simulation program. Finally, an experimental setup is designed for a conventional boost PFC circuit and the results obtained from the experiments are compared with the simulation ones. By this way, a deeper understanding of power quality is supplied to electrical engineering students via simulation and experimental studies and a computer application is integrated into undergraduate power electronics courses. It is expected that, this work will be useful for students and researchers who are interested in studying and researching power quality and single-phase boost PFC circuits.

A review of single-phase PFC topologies based on the boost converter

2010 9th IEEE/IAS International Conference on Industry Applications, INDUSCON 2010, 2010

The need for solid-state ac-dc converters to improve power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input ac mains, and precisely regulated dc output have motivated the proposal of several topologies based on classical converters such as buck, boost, and buck-boost. Additionally, novel control techniques dedicated to PFC have also been introduced, motivating the manufacturing of commercial integrated circuits to impose sinusoidal currents in the front-end stage of switch-mode converters.

Design and Implementation of Single-Phase Boost PFC Converter

Journal of Engineering

In this paper, a single-phase boost type ac-dc converter with power factor correction (PFC) technique is designed and implemented. A current mode control at a constant switching frequency is used as a control strategy for PFC converter. The PFC converter is a single-stage singleswitch boost converter that uses a current shaping technique to reshape the non-sinusoidal input current drawn by the bulky capacitor in the conventional rectifier. This technique should provide an input current with almost free-harmonics, comply with the IEC61000-3-2 limits, and a system operates with near unity power factor. The other function of the boost converter that should beaccomplished is to provide a regulated DC output voltage. The complete designed system is simulated in MATLAB/SIMULINK and a hardware prototype has been built using analog devices. Simulation results and experimental results are presented to validate the proposed system.
