ソリューション

Uninterruptible Power Supply (UPS) systems are widely used to safeguard power supply for critical components in a myriad of applications ranging from telecommunications and data centers, to various industrial facilities. These systems ensure reliable voltage supply by providing a filter function in addition to compensating for short-term power outages from the grid.

There are typically two main configurations for UPS systems, offline and online. Offline systems are connected in parallel to the main supply line and provide support to the main line. Differently, online systems sit on the main supply line itself and can provide better performance and power quality, being common in higher power or more demanding applications.

onsemi's long-term expertise and leading role in power management and conversion helps customers across the globe develop uninterruptible power supply (UPS) systems at the cutting edge of technology, maximizing power quality and reliability to the loads while reducing cost of ownership. Our Silicon Carbide (SiC), SiC/Si hybrid and IGBT module technology, as well as our broad offering of advanced discrete SiC MOSFETs, IGBTs and mid-voltage SJ MOSFETs, together with versatile gate driver, power conversion, sensing and protection ICs families help address the diverse requirements of low, medium, and high power uninterruptible power supply (UPS) designs.
