Support of motherboard MOD-MB-HB-0900V-40A with TI control card TMDSCNCD280039C for MPPT Boost

We have TI control card TMDSCNCD280039C for the full motherboard MOD-MB-HB-0900V-40A. Unfortunately, the Speedval Graphical User Interface (GUI) not provide the desired output voltage and current. We just configured in Synchronouse Boost Mode.

Hello,

Can you provide some additional details? What is your input voltage that you are supplying to the boost board? What happens when you click "Run"? Does it boost to a different voltage than expected, or does it not do anything?

Hello,

Yea, my input supply voltage is 120V. When I click "Run," the fan is working. However, their is no output voltage and not temp. I also checked with an oscilloscope; their is nothing. The GUI is connected. I have used a TI-controlled card and flashed it successfully.

Hello,

Is the GUI reporting 120V on the input and output? Even without the PWMs operating, the the output should match the input for a boost configuration. Are there any faults being reported on the GUI, or indicated by the LEDs on the gate driver? If so, try clearing them using the reset button on the motherboard. Are both both jumpers installed in the correct position to utilize the PWM signals coming from the controller as shown below?
