Damage of CAB425M12XM3 Module

Dear Folks,

I have been working on the Inverter Design for Traction Application using various Discrete & Integrated Modules. Later, found CAB425M12XM3 module with sheer compactness and high power density. Compatible Evaluation Gate Driver Card was also found. Started to integrated these units and load test the modules with resistive and inductive loads. Surprised to find that the modules were damaged (DC Short) by switching from 0 to 40A AC load and later from 40A to 75A load. Even the Gate Drivers were also damaged with fault enabled.


Trying to work on disabling the fault and bring on track this module.


Has someone faced the same problem? If so, please reply.

    Hi Varun,

    Happy to assist you. Could you share with the more specifics on the setup? For instance, did you use the Wolfspeed driver (CGD12HBXMP) ? What was the cooling method used? What deadtime was utilized? Did you enable overcurrent protection? Do you have any waveforms or pictures of the setup to share?

    Thanks,

    Dan
