Power semiconductor IC supplier onsemi of Phoenix, AZ, USA says that its EliteSiC family of silicon carbide (SiC) power modules has been selected for Kia Corp’s EV6 GT model. The electric vehicle (EV) accelerates from zero to 60mph in 3.4 seconds and reaches top speed at 161mph. Within the traction inverter of a high-performance EV, the EliteSiC power module enables high-efficiency power conversion from the DC 800V of the battery to the AC drive for the rear axle. onsemi continues to collaborate with South Korean automakers Hyundai Motor Company and Kia Corp (HMC/KIA) to use EliteSiC technology for the upcoming high-performance EVs based on HMC/KIA’s Electric – Global Module Platform (E-GMP).
onsemi says that its high-power-density SiC power module delivers the package technology to minimize parasitics and thermal resistance and offers robust package reliability using innovative interconnects. This leads to reduced power losses associated with DC-to-AC conversion along with reduced size and weight of the traction inverter, increasing performance and EV range by 5%.
onsemi notes that its power module technology delivers power traction solutions through the firm’s decades of packaging expertise in high-density power solutions for automotive applications. Packaging technology alongside an evolutionary path from planar to trench cell structures in SiC enable onsemi to provide highly robust and reliable solutions to HKMC/KIA.
“Our collaboration with HMC/KIA is rooted in the superior performance of our EliteSiC technology,” says Simon Keeton, executive VP & general manager of onsemi’s Power Solutions Group. “As important is our quickly growing, vertically integrated SiC supply chain that allows onsemi to plan for the necessary scale to support high-volume production for EVs.”
