The UPS system is an important backup power source for many applications such as telecommunicationskèo hôm nay, data centers, hospitals, and industrial facilities. In data center power supply systems, modular UPS has received increasing attention in recent years due to its small size, high power density, and ease of expansion and maintenance. Compared with traditional silicon-based power devices and other options, using SiC based technology to design UPS systems can greatly improve the energy efficiency of these infrastructure operations. In recent years, with the development of silicon carbide materials and devices, silicon carbide diodes have been first applied to UPS. Due to SiC; The advantages of MOSFET in high temperature, high voltage, high switching frequency, and high power density effectively reduce the power loss of the system, simplify the topology structure of the converter, and improve the system efficiency. With the rapid development of data centers, silicon carbide devices are gradually being used in their power supply.

Industrial motors are also major energy consumerstỷ lệ kèo, including industrial low-voltage drives, servo drives, heat pumps, and air conditioners, accounting for a total of global annual electricity consumption; 45%  above. Currently, Europe, North America, and China have established strict energy efficiency standards to reduce motor energy consumption. According to European energy efficiency regulations, since; Starting from July 1, 2023, the prescribed motor ratings will be mandatory to meet IE4 energy efficiency level 2.2; kW  The transition of the four pole motor from IE2 to IE3 reduced losses by 15.2%, and from IE3 to IE4 reduced losses by 21%, resulting in an overall efficiency increase of 89.5%. The need to redesign the system from Si based devices to SiC devices will help achieve energy-saving goals, so the growth rate of SiC demand in the industrial motor field will be higher than in other fields in the future.
