Uninterruptible power supply (UPS)

Today’s uninterruptible power supply (UPS) systems face a wide range of challenges. Overcoming them requires an increase in output power and power density as well as energy efficiency and reliability.

For all UPS power supply applications, high-quality products from Infineon and International Rectifier provide you with solutions targeting the entire power range of UPS applications. Equipped with our semiconductors, UPS systems can achieve best-possible power conversion efficiency and cutting-edge power density.

The benefits: cost reduction and fewer number of passive components – regardless of the topology used.

By choosing Infineon for UPS applications you get solutions that fulfill the latest market requirements. For example, modularization of UPS brick units, a prerequisite for implementing scalable UPS systems in data centers. A second example: multilevel topologies that achieve higher efficiency and performance. From highly functionally integrated gate drivers, to microcontrollers, to discrete IGBTs, to power MOSFETs, to 3-level IGBT modules, Infineon’s portfolio covers UPS needs in a diverse range of applications, including telecom, data centers, servers and  industrial Automation.
