Advanced semiconductor components especially created for automotive applications are silicon carbide (SiC) power devices. SiC power devices are becoming more and more used in the automotive industry because they have many advantages over conventional silicon-based power devices.
Silicon carbide, a compound semiconductor material with remarkable electrical and thermal properties, is used to create SiC power devices. In comparison to silicon-based devices, these devices can withstand higher voltages, temperatures, and switching frequency.SiC power devices are more efficient because they have lower conduction and switching losses.
This efficiency upgrade decreases energy usage, increases the overall vehicle range, and prolongs the battery life in electric cars (EVs).SiC power devices have a higher operating temperature range than silicon-based counterparts. With better thermal management and more compact designs made possible by this capability, automotive systems will have higher power densities and greater reliability.
Due to SiC devices’ improved switching properties, switching losses are decreased and switching speeds are increased. In high-frequency applications like motor drives and power converters, this capability is essential for improving system performance. Because SiC power devices can operate at greater voltage levels, high-voltage applications in automotive systems have been developed.
This capacity is especially useful for traction inverters, EV charging stations, and other high-power systems. SiC’s better material qualities allow for the building of more compact and lightweight power electronic devices. This benefit is particularly relevant for automotive applications, where optimizing vehicle performance and economy depends heavily on weight and space restrictions.
Automotive systems such as EV powertrains, on-board chargers, DC-DC converters, inverters, and more are finding use for SiC power devices. They provide increases in system reliability, power density, and overall system efficiency.
SiC power devices are anticipated to play a critical role in allowing the next generation of energy-efficient and high-performance automobiles as the automotive industry continues to migrate towards electrification and better efficiency standards.
The global automotive sic (silicon carbide) power device market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
New silicon-carbide (SiC) high-power modules were introduced by STMicroelectronics with the goal of enhancing the efficiency and range of electric vehicles.
Leading mobility provider DENSO CORPORATION stated that it had created the first inverter ever to use silicon carbide (SiC) semiconductors. This inverter will be utilized in the new Lexus RZ, the automaker’s first specifically designed battery electric vehicle (BEV) model, which is built within the eAxle, an electric driving module created by BluE Nexus Corporation.
