ROHM, Mazda, and Imasen Sign a Joint Agreement to Develop Inverters for e-Axle Using ROHM SiC Power Modules

ROHM, Mazda, and Imasen Sign a Joint Agreement to Develop Inverters for e-Axle Using ROHM SiC Power Modules ROHM has signed a joint development agreement with Mazda Motor Corporation (Mazda) and Imasen Electric Industrial Co., Ltd., (Imasen) for inverters and SiC power modules to be used in the electric drive units of electric vehicles,including e-Axle. As the ‘heart of the EV’, e-Axle integrates a motor, reduction gearbox, and inverter into a single unit that plays a large part in determining the driving performance and power conversion efficiency of electric vehicles. SiC MOSFETs in particular are expected to improve efficiency even further. ROHM will carry out joint inverter development for e-Axle by participatingin a ‘cooperative framework for the electric drive unitsdevelopment and production’ with companies such as Imasenand led by Mazda. At the same time, ROHM will contribute to the creation industry-leading compact, high efficiency electrical units by developing and supplying advanced SiC power modules that provide improved performance. Through this collaboration, ROHM will develop even more competitive SiC MOSFETs and modules by working backwards from the finished vehicle to understand the performance and optimal drive method required of power semiconductors. Besides creating new value through mutual understanding between car and device manufacturers, the ...
