Abstract :
This paper presents the reactive power compensation with UPS. The most effective power quality improvement solution is analyzed in an uninterruptible power supply systems. The conventional UPS has three stages i.e rectifier converts AC to DC, Battery to store DC and Inverter to convert DC to AC. A novel technique has implemented in off-line UPS. The power is delivered to load via by-pass switch when main supply is available. Inverter does not operate during this period. So inverter function is same as conventional inverter. To overcome this problem, static change over switches has proposed. Hence it will get better voltage regulation and loss less in distribution system. The performance of simulation result is analyzed using MATLAB/SIMULINK.
