How to connect the Gate Driver Board with the Power Module CAB016M12FM3

JunMing

Hi,

I am using SiC power module CAB016M12FM3 for an inverter. And I have bought the "Dual Channel Differential Isolated Half Bridge Gate Driver Board" CGD1700HB2M-UNA. I learned from the product introduction that CGD1700HB2M-UNA is compatible with CAB016M12FM3, but I have some trouble when connecting them.

Do you know how to connect CGD1700HB2M-UNA with CAB016M12FM3? I noticed that their pin spacing is not the same. Should I design a PCB board specially? Or maybe I can buy a connection board from Wolfspeed directly?

Please let me know if you have any questions, comments, or issues.

Thanks!

Hi JunMing,

The FM3 power module is intended to be press-fit into a PCB to route the power and signal connections for the application. The CGD1700HB2M-UNA gate driver board would mount to this PCB. The gate driver does not connect directly to the module.

Here is an example of the arrangement for dynamic evaluation of the module (double-pulse testing):
