As the demand for compute power in AI, digital and cloud services grows remarkably, higher power levels are required in server power supplies and processors. In the meantime, power redundancy is critical to ensuring operational continuity and reliability of data centers. The UPS converts AC power from the power grid into DC power to charge the battery. At the same time, the DC power is also converted back into AC power to supply power to the system. The UPS seamlessly switches during a power outage caused by a power grid failure to ensure power supply security. The use of SiC devices in server power supplies and UPS power supplies can increase the switching frequency of power modules, reduce the size of passive components to increase power density, reduce power loss with higher efficiency, and meet system cooling requirements with lower-cost thermal management.
UPS Block Diagram
Uninterruptible power supplies (UPS) ensure power supply security by converting AC power in a battery or battery pack into AC power, including AC/DC and DC/AC circuits. They are used in many fields, including industrial manufacturing process, telecommunication, data center, medical equipment, and small office or home office environments.

Server Power Supply Block Diagram
Server power supplies are mainly used in the data center scenario to supply power to IT equipment such as server, storage and switch. Server power supplies are the departure point and the destination point of the entire data center power supply and distribution system, and are composed of AC/DC and DC/DC circuits.
