Uninterruptible power supply (UPS) systems stabilize power by activating during outages and protecting against power fluctuations. Maintaining seamless operational continuity even during power outages, these solutions prevent data loss and hardware damage.

What are the different types of UPS?

UPS systems come in three main varieties. Each type provides unique benefits tailored to meet the specific needs of a data center environment.

Standby UPS

 

The standby UPS, or offline UPS, offers basic power protection. It remains idle until a power failure is detected, at which point it switches to battery power. This type suits smaller, less critical applications where momentary power interruption is acceptable during the switch.

Line-interactive UPS

 

Line-interactive UPS systems systems offer more advanced protection by correcting minor power fluctuations without switching to a battery. This approach improves efficiency and prolongs battery life, making it a good choice for medium-sized applications that require better voltage regulation.

Online double conversion UPS

 

The double conversion UPS provides the highest level of protection by continuously converting incoming AC power to DC and then back to AC. This process eliminates all power quality issues, including outages, sags, surges, and noise. Because it provides an uninterrupted power supply, it is ideally suited for high-density battery backup applications where even a short interruption cannot be tolerated.

Advanced UPS technologies for high-density workloads

Expansion into advanced UPS features to meet specific data center needs is essential given the rapid technological acceleration.

Fuel cells

Fuel cells chemically convert energy into electricity efficiently and reliably, making them ideal for high-density data centers that require continuous power for operational reliability. Among the different types, proton-exchange membrane (PEM) fuel cells use hydrogen as their fuel source and feature a solid polymer electrolyte, while solid oxide fuel cells (SOFCs) use a ceramic compound and operate at much higher temperatures.

Figure 4: Phases 2 and 3 are short-to-medium-term goals for data centers' energy independence reducing diesel generators' starts from the microgrid facility and replacing them with PEM and SOFC fuel cells as backup and prime power sources, respectively.

Capable of exceeding 60 percent energy efficiency, fuel cells surpass diesel generators, which are only 30 percent efficient. When hydrogen is used, the only byproducts are water and heat, aligning with decarbonization goals. Data centers may further utilize fuel cells to phase out standby generators (see Figure 4) and reduce carbon emissions, supporting the industry's decarbonization goals.
