UPS configuration

Advantages - Output Isolation Transformer



No DC component in output (galvanic isolation by transformer)

Transformer less UPS – DC components are controlled electronically  

Lower DC voltage – less number of batteries per string (30-32 blocks)

Less cost for same type of batteries and back up time Transformer less UPS – More battery blocks, connections etc Transformer based UPS – 2.7 X Nominal current Ph-Ph - 4 X Nominal current Ph-N / G Transformer less UPS – 2.2 X Nominal current 

No neutral current back to the mains in case of unbalanced load in Double conversion mode

 

Better management of unbalanced load.

A Zig-Zag transformer will share an unbalanced load on the three inverter bridges Transformer less UPS – inverter legs may see unbalanced load ( different leg operates at different load % - Components stress level are different) improves battery lifetime through less ripple

Better management of non linear load

(low level harmonics are short-circuited) GE Critical Power SG 10-40 kVA Presentation Page 7 – 2013
