About Uninterruptible power supplies (UPS)

Factors such as the rising trend towards the internet of things (IoT) and smart buildings, a growing number of datacenters across the globe, virtualization, and cloud computing are expected to drive the UPS market globally in the coming years. Uninterruptible power supplies provide power to critical loads in the event of a power failure. Unlike emergency generators, UPS systems provide power immediately, but only for a short period of a few minutes ¨C until a backup power supply comes online or until the load completes its shutdown sequence. While continuity of power supply is an important functionality, it is not the only one: for example, a UPS system can also filter voltage spikes, voltage drops, or noise and ensures a constant frequency or guarantees a certain power quality.

The applications of UPS systems are many and varied: they are used in medical, commercial, and industrial facilities, as well as in many locations of the IT and telecommunications infrastructure, ranging from personal computers to datacenters. Infineon covers these applications and more with our powerful and efficient solutions for both online and offline UPS.

Infineon's UPS solution portfolio

Today¡¯s UPS systems introduce a wide range of challenges. Overcoming them requires an increase in output power, energy efficiency, and power density. We offer complete system-level solutions and high-quality products for diverse UPS applications. Equipped with our semiconductors, UPS applications can achieve the best-possible power conversion efficiency and cutting-edge power density. The benefits are cost reduction and fewer passive components ¨C regardless of the topology used.

Our solutions and products for UPS applications fulfill the latest market requirements. This includes the trend of modularization of UPS brick units due to scalable power demand from datacenters, as well as the topology shift from two-level to three-level to achieve higher efficiency. Our products are suitable for any kind of Uninterruptible power supplies in telecom, datacenter, server, or industrial automation environments. Our microcontroller solutions fulfill the control and power conversion requirements to enable UPS market needs. Finally, Infineon¡¯s portfolio of Wi-Fi and Bluetooth? combos enables UPS proper connectivity for monitoring.

The differences between online and offline UPS

Uninterruptible power supplies (UPS) are divided into two main categories: online UPS and offline UPS. There are several distinct differences between the two types. The most distinct difference is that online UPS is directly connected to the AC main and charges its battery from there, whereas the offline UPS only connects to the other systems once the main power fluctuates or there is an outage. Basically, it boils down to online UPS providing backup power with no switchover time, whereas the offline UPS requires a very short switchover time. For this reason, applications that require constant power such as medical devices or servers usually use online UPS systems, whereas the less expensive offline UPS systems are used mainly in offices and homes.

Further, Infineon divides its offering for offline UPS into two types: high- and low-frequency transformers. Our low-frequency solutions are meant for 50 or 60 Hz iron core, while our high frequency offering is for 20 - 50 kHz ferrite core.

Infineon offers products and system solutions for online UPS, and both high- and low- frequency transformer offline UPS. Navigate to your preferred type from this page to browse our portfolio.
