ROHM has Introduced Reference Designs for Three-Phase Inverters Featuring New SiC Power Modules
18 March 2026 ROHM has announced it has released reference designs "REF68005", "REF68006", and "REF68004" for three-phase inverter circuits featuring EcoSiC brand SiC moulded modules "HSDIP20", "DOT-247", and "TRCDRIVE pack" on its website. The company says designers can use the data provided in these reference designs to create the drive circuit boards. When combined with ROHM’s SiC modules, these designs can help reduce the person-hours required for device evaluation. In high power conversion circuits, while SiC power devices contribute to higher efficiency and reliability, they can increase the workload associated with peripheral circuit and thermal design. The reference designs released by ROHM can support output power levels up to the 300kW class, facilitating the adoption of SiC modules across a wide range of automotive and industrial applications. Three types of SiC modules compatible with these reference designs are already available for purchase through online distributors such as DigiKey and Farnell. The reference designs are intended for users to utilise the publicly released design data, customers can obtain a reference design board or evaluation kit by contacting a sales representative or visiting the contact page on ROHM’s website. (Quantities are limited.) Details of SiC modules currently available through online distributors can be found below. The company says it can also provide various support resources to facilitate quick evaluation and implementation of its products and its comprehensive solutions, including simulation and thermal design support, and can provide valuable assistance in component selection.
