ROHM has released reference designs “REF68005”, “REF68006”, and “REF68004” for three-phase inverter circuits featuring EcoSiC brand SiC molded modules “HSDIP20”, “DOT-247”, and “TRCDRIVE pack” on ROHM’s website. 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 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 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.
About Reference Designs
These reference designs are intended for users to utilize the publicly released design data. If you would like to obtain a reference design board or evaluation kit, please contact a sales representative or visit the contact page on ROHM’s website. (Quantities are limited.)
