Evolution
Simple, but low efficiency
Not widely used anymore
2-level Inverter
”Switching voltage” =
100% x Vbus (e.g. 900V)
=> High switching losses (100%)
Most used topology
in industry
3-level Inverter
High and flat efficiency curve
Used in Galaxy VM and VX
Future?
4-level Inverter
”Switching voltage” =
33% x Vbus (e.g. 300V)
=> Lower switching losses (33%)
”Switching voltage” =
50% x Vbus (e.g. 450V)
=> Medium switching losses (50%)

ECO mode supply to load on bypass
mains power without power conditioning
and provides highest efficiency of 99%.
ECOnversion mode provides near double
conversion performance at near ECO mode
efficiency. ECOnversion provides power
conditioning at efficiency 98% to 99%.
This unique flexibility of Galaxy V series allows customer to operate the UPS in any of the above
mode depending on load profile, site environment and schedule during the lifecycle of the UPS.

18. Why Lithium?
Customers are facing some difficult challenges with respect to UPSs
These challenges are driving the need for specific UPS requirements, including:
• Reduced UPS footprint and weight to allow for a more effective, flexible use of space
• Reduced cooling capacity
• Increased energy storage availability and ability to predict UPS failures
• Extended UPS life and reduced maintenance overhead
