At present, an 800V high-voltage silicon carbide electric vehicle consumes approximately how many pieces of substrates, taking 6 inches as an example

Tianyue Advanced: Dear investors, hello! Silicon carbide power devices have outstanding advantages in voltage resistance level, switching loss, etc., which are helpful to realize the lightweight and high efficiency of the power electronic drive system of new energy vehicles. Therefore, they will play a more important role in key electronic control components such as the main drive inverter of new energy vehicles. Especially in the 800V high-voltage platform, the advantages of silicon carbide technology are more obvious. The substrate is the basis of silicon carbide semiconductor devices and a key link in the industrial chain. A research report pointed out that according to the comprehensive calculation of silicon carbide technology used in the main drive, DC-DC, OBC and other aspects of electric vehicles, a 6-inch wafer can be used for 2 electric vehicles, but the use of silicon carbide substrates in different models varies due to different architectural designs and the number of uses in specific parts. Thank you for your attention to the company!
