AUTOMATIC POWER FACTOR CONTROLLER CUM RECTIFIER
Project Aim
This project discusses the need for power factor correction and provided a suitable do-it-yourself (DIY) solution that could be used for small-scale industries and establishments.
In small industrial units where the load is contributed by a number of inductive appliances, it is cumbersome to switch in capacitor banks at the power entry poin ....etc

A Single-Phase High Power Factor Rectifier,
Based on a Two-Quadrant Shunt Active Filter



Abstract

This paper presents a new technique to improve the
input power factor of a single-phase rectifier followed by an
inductive filter. It consists in the employment of a two-quadrant
active power filter, based on a conventional bidirectional DC-DC
converter, connected to the output side of the diode bridge. This
technique allows the extension of this rectifier range operation in
the continuous conduction ....etc

Abstract
This work describes a novel method in improving the
input current total harmonic distortion (THD) as well as the power
factor of a three-phase suppressed-link rectifier-inverter circuit.
This proposed method makes use of only three bi-directional low
power static switches with a relatively simple gating circuit. This
paper illustrates how the proposed method is superior in reducing
the input current THD of a rectifier-inverter set to about 5%,
which is in line with the requirements of IEEE standard 519–1992.
This is a ....etc

Power Factor and improvement



Capacitance
Xc=106/2 fC = V/I
Capacitor current = kVAr x 1000 / V
The opposition to current in a capacitor is termed as capacitive reactance. The current in a purely capacitive circuit will lead the voltage by 90.


Effect of low power factor
kW capacity of the transformer is decreased
Cross-sectional area of the busbars and the switchgear must be increased
The kVA capacity of the alternator is more

3-Phase Power Factor Correction, Using Vienna Rectifier Approach and Modular Construction for Improved Overall Performance, Efficiency and Reliability
1.0 Abstract:
While applications for 1-Phase PFC are now familiar and prevalent, the same is not the
case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains
should be candidates of 3-Phase power factor correction, because several advantages
ensue, both to the user of the equipment and to the utility. The Vienna Rectifier approach
to achieve 3-Phase ....etc

An Integrated Silicon Carbide (SiC) Based Single Phase Rectifier with Power Factor Correction



I. INTRODUCTION
Power supplies are one of the most crucial building
blocks of a modern society, converting high-voltage AC
into low-voltage DC for use in electronic circuitry in office
equipment, telecommunication, and consumer electronics.
Over 2.5 billion AC/DC power supplies are currently in use
in the United States alone, about 6 to 10 billion are in use
