Advantages of a Transformer-Based UPS System
Recent Whitepapers have point out the advantages of transformerless UPS: less weight, flexible installation, energy efficiency, money savings.
However, transformerless UPS are better suited for large energy efficient applications where the tolerance for downtime is acceptable under certain circumstances and where there is a transformer installed somewhere else in the electric path.
This literature has made it sound like transformer-based technology in UPSs is obsolete and should be avoided.
Nonetheless, there are still critical applications requiring a nine nines rate which in turn need a transformer-based UPS.
For that reason, we are listing the advantages of transformer-based UPS.
