UPS?

Firstly, when one brings up UPS, what comes to mind? The delivery company is what I thought of before being exposed to the idea of UPS in an electrical sense. It is an uninterruptible  power supply (UPS).

What is a UPS system all about?A UPS system provides emergency power to load when input power source, typically the utility mains, fail! Basically its just a temporary power supply mostly used to power data centers and places of that sort to prevent the loss of data and the equipment being damaged.  There are many types of UPS systems, the one we are looking are specifically called the double-conversion ups.
Now another few questions would come to mind, what is a double conversion UPS system and how does it work? The basic principal of double conversion, take the AC source supply and turns it into a DC feed and then converts it back into an AC source.

Why use a double conversion UPS system? It provides the highest level of protection against the weakest spectrum of power. The incoming feed is of AC source and is converted into a regulated DC voltage. From this voltage, a new AC volatege is regenerated, providing continuous, clean and tightly  (between =/- 2-5 degrees celcius). The batteries are then connected to an inverter, so no power transfer switches are required. When power loss occurs, the rectifier cuts the circuit out and the batteries keep the power steady and unchanged. Upon restoration of the power, the rectifier resumes carrying most of the load and begins charging the batteries.

The advantages? One might be wondering why the need to use a double conversion system as opposed to other systems. One of the main advantages of a double conversion system is the ability to provide an electrical firewall between the incoming utility power and sensitive electrical equipment. This is crucial when dealing with the prevention of data loss and other issues of similar concern.
