Quick tips for differences in energy efficiency between online “double-
conversion” technology and online “on-demand” technology
This quick tip first defines online “on-demand” technology and online “double-conversion” technology. It then contrasts the
energy efficiency performance delivered by these two technologies, each of which uses a different method to ensure a reliable
power source for continuous data center operations.
Online “double-conversion” technology
Online double-conversion is currently the technology that most data centers use for their uninterruptible power supply (UPS)
systems. In this type of UPS, the inverter is always on; it continuously converts AC to DC and then DC to AC. This generates a
pristine, or very low-distortion, sinusoidal waveform; however, efficiency is significantly lower than with online on-demand.
Online “on-demand” technology…plus double conversion
Online on-demand is an energy efficient technology that allows incoming power to connect directly to the load through
protected circuits when the incoming power is within specifications. When the power is not within specifications, the double-
conversion technology takes over to regulate the incoming voltage to an acceptable level for the load. Both online on-demand
and double-conversion modes protect the critical load from voltage fluctuations and from damaging transients that can originate
at the utility. And in the event the power goes out completely, the energy from the battery is converted to provide power to the
load until the utility returns service or until a graceful equipment shutdown becomes necessary.
