Main Inverter (Traction Inverter)
Vehicle electrification continues to advance as a countermeasure against global warming.
For inverter units used to generate AC voltage from battery DC for driving motors, greater efficiency along with higher frequencies and voltages are required to meet the need for increased miniaturization while extending vehicle cruising range.
ROHM overcomes barriers difficult to achieve with conventional devices through a broad lineup of SiC solutions.

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.

Reference Designs
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.
