Hello DrChandra,

Thank you for your interest in these products. The CGD1700HB2M-UNA gate driver designed by Wolfspeed can be used to drive these power modules in early system evaluation and commissioning. Furthermore, the design files for this gate driver are available for download, so the design can be modified to support your application needs. These gate drivers were used by Wolfspeed to both characterize the devices you mentioned and for reference designs such as the CRD200DA23N-GMA.

The Texas Instruments UCC21710 gate driver IC used on this gate driver has a working voltage rating of 1500 V and the isolated power supplies have a functional barrier isolation of 2.4 kV. Note that higher voltages can be achieved with these components in a controlled laboratory environment given that operators recognize that the elevated voltages will result in a reduced component lifetime and should not be employed for safety isolation.

We are also actively working on a gate driver solution to support high bus voltages. This design uses RECOM RHV2 series of power supplies and Texas Instruments ISO7841x (in the DWW package) to achieve a higher working voltage rating. This design is expected to be released in the coming months.

Thanks,

Chris N.
