New standards by the U.S. Deparment of Energy suggest how to improve UPS energy efficiency

At the end of December the U.S. Department of Energy (DOE), has issued the first-ever energy efficiency standards for uninterruptible power supplies (UPS). According to the DOE, the new UPS standards will mean 87 billion kilowatt-hours of electricity saved over the next three decades. This represents an energy savings of 15 percent relative to the electricity consumption of these products in the absence of an efficiency standard.

The department‘s analysis lists variety of technology options that manufacturers can use to improve the efficiency of their products.

„DOE identified three technology options for UPSs that would be expected to improve the efficiency of UPSs. The technologies options are: semiconductor improvements, digital signal processing and space vector modulation, and transformer-less UPS topologies.“

And further:

„Transformer-less UPS designs offer some of the highest efficiencies in the industry with lowered weight, wider input voltage tolerances, near unity input power factor, reduced harmonic distortion and need for components that mitigate electromagnetic interference (EMI) generated by the device.“

For the sake of completeness one must also say, that the DEO did not evaluate transformer-less UPS design because „interviews with manufacturers have shown this to be a limited access technology with select manufacturers holding the intellectual property required for effective implementation.“

However, the DOE does not prescribe how manufacturers should make their products more efficient. The standards are being set in a performance-based manner, allowing manufacturers the flexibility to innovate. Thus, the document can also be interpreted in such a way that transformer-less UPS design is always a future-proof choice in terms of efficiency.

Chris Granda, blogger at Appliance Standards Awareness Project, comments:

„Had DOE included transformer-less design in their analysis, we believe even stronger UPS efficiency standards would have been justified.“

How to choose an UPS for today’s and tomorrow’s demands

In an article published in the December 2016 edition of Inside Networks Alan Luscombe, director at Uninterruptible Power Supplies Ltd. discusses how data center managers can use the latest modular UPS topology to achieve the highest power availability and efficiency.

For many of today’s businesses going offline is not an option. High UPS availability is essential for delivering stable data center services to fulfill these needs. But increasing demand of data center power also puts pressure on the general availability of power.

Therefore facility managers are looking for UPS systems that offer the most efficient possible operation along with the highest availability that can be practically achieved. Luscombe: „Fortunately, evolution in UPS technology, particularly modular UPS solutions, enables implementations that can satisfy both these objectives.“

And further: „While data center and ICT facility operators remain under ever-increasing pressure to achieve near-perfect power availability and efficiency, modern UPS technology offers many tools to help them if it is deployed correctly. Availability can be maximised by using hot-swap modular topology in a redundant configuration. Newer technologies have raised UPS energy efficiency, and this efficiency can be further improved by using Eco Mode if site conditions and ICT equipment allow.“

New energy-saving feature for DPA 500 UPS: Maximum efficiency in all loading conditions

ABB’s Xtra VFI / double conversion mode delivers maximum efficiency by dynamically adjusting the DPA 500 UPS configuration to match the load.

The figure shows how the Xtra VFI operating mode can enhance efficiency when running at a low load level for a Conceptpower DPA 500 modular UPS system with 10 UPS modules (100 kW) and total available capacity of 1 MW.

ABB has announced a significant new energy-saving feature for its DPA 500 uninterruptible power supply (UPS). In Xtra VFI / double conversion mode, the UPS automatically configures the number of modules that are active to match the load power requirements. Modules that are not needed are switched to standby, ready to transfer to active mode if the load increases. The efficiency improvements achieved by this mode of operation are especially significant in low-load conditions.

When a UPS is operating at significantly under capacity, its energy efficiency can be negatively impacted. With ABB’s Xtra VFI operating mode – currently available for the DPA 500 UPS only – this problem is solved. Xtra VFI mode is a smart way to minimize losses and improve efficiency safely when running in double conversion mode.

When Xtra VFI mode is enabled, the UPS automatically adjusts the number of active modules according to the load power requirements. Modules that are not needed are switched to a standby state of readiness, primed to transfer back to active mode if the load increases. The efficiency improvements achieved by this mode of operation are especially significant when the load is less than 25 percent of full UPS system capacity – an operating condition in which traditional UPS systems fare poorly.

The DPA 500 calculates the optimal loading for each of its modules, taking into account the desired redundancy level selection and other set parameters. To ensure smooth operation in each application, the highest expected load step can be set by the user, as can the number of redundant modules that should be active at any time. Hysteresis prevents the modules from switching on or off when close to the threshold. To increase reliability, extend service life and equalize ageing, the system rotates the modules between active and standby mode at fixed intervals.

Should there be a mains failure or other abnormal situation, all modules revert to active mode within milliseconds.

Since its recent introduction to the market, the DPA 500 UPS has proven very popular: ABB’s decentralized parallel architecture (DPA) is the most advanced approach to modularized UPS available. With DPA, each standardized module has all the hardware and software needed for autonomous operation. Modules can be swapped without powering off. Systems can be scaled up by simply adding more modules. Because of its very flat efficiency curve, the DPA 500 is very efficient in most operating working regimes and Xtra VFI mode increases this capability even further.

The Xtra VFI feature will be of special interest for large and colocation data center users where energy efficiency is a topic of great interest. A pilot installation of Xtra VFI mode has been running smoothly and effectively for some time in a large data center in Germany.

Recommended reading: How static switches contribute to power continuity

There are circumstances under which even the best of UPSs are unable to provide full on-line protection. Even though modern modular UPSs can achieve as much as 99.9999% availability, the chance of a UPS failure does still exist.

This is where static switches are invaluable. A static switch is used to transfer the load between the UPS inverter output and a bypass supply. This article by UPS Ltd explains in more detail how static switches contribute to power continuity.

The static switch – typically using semiconductor silicon controlled rectifiers (SCRs) rather than mechanical switching elements – is an intelligent device that decides whether to use the UPS inverter output or the raw mains to supply the load. This decision is made by logic within the switch and/or the UPS’s control system, which continuously monitors the bypass and inverter voltages.

Thus, static switches are essential for ensuring no-break transfers between inverter and bypass, and for ensuring personnel safety during on-line UPS maintenance and repairs.
