「The new inverter is installed in the new eAxle of BluE Nexus Co., Ltd., a joint venture with AISIN CORPORATION for the electric drive system business. Using proprietary SiC (silicon carbide) power semiconductors and double-sided cooling technology, it reduces power loss by approximately 70% and the core module size by approximately 30% compared with the previous model, achieving power density at the world’s highest level.」
The SiC power semiconductor has advanced from market launch and vehicle installation to new performance achievements in an inverter for the new bZ4X, including an approximately 70% reduction in power loss and an approximately 30% reduction in core module size. - FY2023AchievedAnnual report
「We launched our first inverter using SiC (silicon carbide) power semiconductors. The product was incorporated into the “eAxle” of BluE Nexus Co., Ltd. and installed in the LEXUS “RZ,” the first dedicated battery electric vehicle model from LEXUS.」
The SiC power device has progressed from the development stage to market launch, mass production, and installation in the LEXUS RZ. - FY2018First statedAnnual report
「As a specific initiative, we are developing power devices made from silicon carbide (SiC).” “To reduce this energy loss, we developed power devices made from silicon carbide (SiC), which generates less heat, and substantially reduced energy loss to one-third.」
The company has disclosed for the first time the development of SiC power devices and the resulting reduction in energy loss to one-third.
