Firstly, load balancing is one of the most important contributing factors in achieving optimal operating efficiency. In a three phase UPS system, each phase works together to carry the critical power load, this load ...

The Different Types of UPS Systems

There are two main categories of uninterruptible power supplies (UPSs) 1, static and rotary. As the name implies, static UPSs do not have any moving parts in their con-verters. Whereas, rotary UPS use mechanical parts that rotate, such as motor/gen-erators, to function. This paper focuses only on static UPSs.
