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

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

Example
Let us suppose ....etc
