MOD-MB-3P-0900V-40A-N interface with TMDSDOCK28335

Amal

Dear Experts,

I am working on building a three-phase voltage source inverter (VSI) using the MOD-MB-3P-0900V-40A-N SpeedVal Kit. I have already purchased the following components:

• MOD-MB-3P-0900V-40A-N (motherboard)
• MOD-PWR-MM-C3M0032120K (power module)
• CGD12HB00D (differential signal adapter)

My application involves switching the VSI at 100 kHz using sinusoidal PWM. I do not wish to use the HVP-56F83783 control card from NXP. Instead, I will use the TMDSDOCK28335 (TI F28335) development board. I plan to keep the TMDSDOCK28335 externally and leave the control card slot on the MOD-MB-3P-0900V-40A-N unoccupied.

Could you please help me with the following:

1. Can I connect the PWM output (0–3.3 V, single-ended) from the TMDSDOCK28335 to the CGD12HB00D, and then use its differential output to drive a suitable gate driver module mounted on the MOD-MB-3P-0900V-40A-N? If so, please recommend a compatible gate driver module.
2. Is it possible to mount the CGD12HB00D directly onto the MOD-MB-3P-0900V-40A-N?
3. How can I take the sensed output voltage and current from the MOD-MB-3P-0900V-40A-N and connect it safely to the ADC inputs of the TMDSDOCK28335?
4. I understand that the MOD-MB-3P-0900V-40A-N requires a 12 V auxiliary DC supply. Do I also need a external isolated DC power supply for the gate driver module?
