“…During the normal mode of operation, the power to the (a) Inverter plus low-frequency transformer [4] (b) Inverter plus HF transformer [2] ( Careful consideration of the system reveals that switch bl q and diode bl D can be eliminated. However, in order to use a low battery voltage it must be boosted to high DC voltage.…”

“…1(d), there are also three operating modes: normal mode, power failure, or outage, mode, and overload or converter fault mode. However, during normal operation, when the AC line is within the preset tolerance, SW1 and SW2 are on and most of the power is supplied directly from the AC line to the load [4].…”

This paper discusses the possible control techniques for UPS and relates these control techniques to the different single-phase UPS topologies found in literature. These possibilities have been mentioned in separate but they have never been put together. Also, techniques for using a low battery voltage are discussed. Finally, a combination of different possibilities of UPS structures and one of the types of operation control is applied to an universal active filter with the function of UPS, with low battery voltage and without any transformer, thus reducing cost and weight. Simulated and experimental results verify the proposed topology.

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. Keywords-rectifier,inverter,battery and bypass switchI.
