Uninterrupted power supply commonly known as home UPS is not only a reserve power device, instead has outgrown as a protector of computer system and its data. This device is suitable for today’s high powered computing requirements and high rush currents and is ideal for extreme power conditions.

UPS basically resides between the critical load and ac power supply. When there is an abrupt change in the voltage level, it restricts the computer from shutting down immediately. Moreover, these are made to provide at least a back up of 20 minutes in case of power failure.

In addition to constant power supply, these are known for clean, stable and regulated supply. This implies that these provide you invariant and nonfluctuating power supply. Since equipments like computers store very important and official data and are sensitive to fluctuations need to be protected with this device.

UPS consists of many components and devices in itself each performing a different function. Inverter is one such device that any UPS include. It is basically used for the conversion of DC voltage into AC voltage. And so depending on that, UPS are of three main types.
