Perhaps the biggest challenge for electric vehicles is maximizing cruising distance given the limited battery power. To this end, it is important to improve electricity consumption in lieu of fuel economy, and SiC devices are considered essential in achieving this.
Integrating SiC devices allows ROHM to improve efficiency while contributing to greater miniaturization through high frequency drive and achieve higher battery voltages in key applications for electric vehicles, including the main inverter, onboard charger, and DC/DC converter.

ROHM Solution Simulator
ROHM Solution Simulator is a new web-based electronic circuit simulation tool that can carry out a variety of simulations, from initial development that involves component selection and individual device verification to the system-level verification stage. This makes it possible to quickly and easily implement complete circuit verification of ROHM power devices (i.e. SiC) and ICs (e.g. driver and power supply ICs), in simulation circuits under close to actual conditions, significantly reducing application development efforts.

A system-level evaluation board that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers. For example, it has been confirmed that all the products equipped with the product meet CISPR25 Class-5 standards in operation with regard to EMC standards, which are important factors in incorporating the product into automotive equipment. In addition, system-level evaluation and design data can be downloaded so that customers can use it as a reference for their designs. ROHM will continue to offer a wide range of solution evaluation boards in the future.
