ROHM signed a joint development agreement with Mazda and Imasen Electric for e-Axle inverters using silicon carbide power modules.
According to Rohm, the application of SiC in electric vehicles is a major trend in the future.
ROHM Corporation is one of the world's leading semiconductor manufacturers, with a capital of 86,969 million yen (as of March 31, 2014), and its headquarter is located in Kyoto, Japan.
Many other major manufacturers also plan to cooperate with Japanese semiconductor manufacturer Rohm to develop semiconductor components for electric vehicle drive equipment.
At the same time, ROHM will participate in the Electronica 2022 in Munich to showcase future-oriented electronic solutions.
Mazda has launched electric drive unit research and development and production cooperation, and recently stated that the company plans to complete the electrification of all models by 2030, and is currently cooperating with a number of partner companies to carry out a series of electrification-related research projects, including electric drive projects.
Silicon carbide inverter is one of the core components of electric drive.
Mazda (Mazda), full name Mazda Corporation (Japanese: マツダ Co., Ltd., English: Mazda Motor Corporation), is a Japanese multinational automobile manufacturer listed on the Tokyo Stock Exchange (TYO), the 2020 Fortune Global 500 Ranked 400th.
Mazda, one of the world's top 500 companies, plans to invest US$10.6 billion to transform into electrification.
Mazda also said: The range-extended version of the MX-30 with a rotary engine will be available in 2023.
In July this year, Imasen Electric Manufacturing Co., Ltd. and Mazda Corporation established a new joint venture project .
As early as May this year, Anson said: Weilai's next-generation electric vehicle will use its latest SiC power module; in August this year, Infineon launched an automotive-grade silicon carbide power module suitable for electric vehicle traction inverters; Hitachi Energy Launched SiC modules for electric vehicles in May this year.
As the core of the motor, the high-tech SiC module has low noise and can greatly increase battery life. Obviously, the competition among enterprises for SiC power modules is intensifying.
Compared with the first-generation semiconductor materials silicon (Si), germanium (Ge) and the second-generation semiconductor materials gallium arsenide (GaAs), gallium phosphide (GaP), GaAsAl, GaAsP and other compounds, SiC has a wider band gap , stronger high temperature resistance, higher switching frequency, lower loss, and better stability, and is widely used to replace silicon-based materials or applications where silicon-based materials are difficult to adapt to;
· the entire SiC industry chain has become the next generation of the new energy industry The foundation of the wave.
· In 2021, it was reported that with the support of electric vehicles, SiC power modules for vehicles in 30 years are estimated to surpass Si by 17 times, and inverters are also predicted to be booming in the industry, and the future can be expected.
· The inverter is a transformer that can convert the direct current of the animal battery into alternating current. It has a function of converting or boosting voltage of 12v or 24v, etc.
