onsemi Uninterruptible Power Supply (UPS)
Reliable, efficient and optimized for mission-critical applications
Uninterruptible Power Supply (UPS) systems protect critical infrastructure such as data centers, telecommunications, industrial facilities, and medical equipment from power interruptions. onsemi provides high-performance discrete devices and power modules including SiC and IGBT technologies, advanced packaging, and isolation solutions to support reliable, efficient UPS designs.
The UPS market is growing rapidly due to cloud technologies, IoT, AI, and increasing demand for data centers. Frequent power outages in regions with aging infrastructure or vulnerability to natural disasters are driving adoption of advanced UPS systems, including e-breakers, with a CAGR greater than 5 percent.
UPS systems operate in offline standby, line-interactive, or online double-conversion modes. Key design considerations include scalability, modularity for hot-swappable modules, digital connectivity for remote monitoring, multilevel safety features, ultra-fast response during outages, and simplified plug-and-play installation.
High-power UPS systems integrate the core UPS system, batteries, switchgear, HVAC, fire and safety equipment, and monitoring systems. onsemi supports advanced features such as 10BASE-T1S Ethernet Controllers and RLS15 Bluetooth connectivity. Higher bus voltages reduce current, minimize heating, and lower power losses, while lithium-ion batteries provide higher energy density, longer lifespan, and fast charging capabilities.
