Abstract
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed UPS sch ....etc

automatic power factor correction by using 8051 microcontroller seminar reports

The thirst for new sources of energy is unquenchable, but we seldom realize that we are wasting a part of the electrical energy every day due to the lagging power factor in the inductive loads we use. Hence there is an urgent need to avoid this wastage of energy.

Before getting into the details of Power factor correction, lets just brush our knowledge about the term power factor . In simple words power factor basically states how far the energy provided has been ....etc

This is a Electrical project work on Automatic power factor correction using micro-controller 8051 and this power factor correction device reads power factor from line voltage and line current by determining the delay in the arrival of the current signal with respect to voltage signal from the function generator with high accuracy by using an internal timer. This device is a very useful device for improving efficient transmission of active power. If the consumer connect inductive load, then the power factor lags, when the power factor goes belo ....etc

ABSTRACT
The traditional approach to power factor correction in a facility is to add capacitors to individual loads such as motors and fluorescent lighting circuits, to add a capacitor bank with switching to a major distribution panel, or to add a capacitor bank with switching to the power input panel from the utility lines. Recently it has been shown that careful selection of high-efficiency motors for a facility can result in new motors with a significantly higher power factor than t ....etc
