ROHM introduces reference designs for three-phase inverters featuring new SiC power modules
Japan-based ROHM has released, via its website, the reference designs REF68005, REF68006 and REF68004 for three-phase inverter circuits featuring EcoSiC-brand silicon carbide (SiC) molded modules HSDIP20, DOT-247 and TRCDRIVE pack. Designers can use the data provided in the reference designs to create the drive circuit boards. When combined with ROHM's SiC modules, the designs help to 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 new reference designs 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.
