LAUNCHXL-F28379D: BOOSTXL-3PhGaNInv power/debugging physical connections

LAUNCHXL-F28379D: BOOSTXL-3PHGANINV

Other Parts Discussed in Thread: BOOSTXL-3PHGANINV

Hi Team,

Here's an issue from the customer may need your help:

I have a LAUNCHXL-F28379D connected to BOOSTXL-3PhGaNInv and the program is only set to PWM output. Using an oscilloscope to measure the corresponding PWM pins, the output waveform is normal, but there is no voltage output from the inverter, what is the reason for this?

Thanks & Regards

Yale Li

    Could you please ask your customer about their questions? Like what example project are they using? Which build level are they working on? How do they check the voltage output on the inverter? Do they connect the power supply to the BOOSTXL-3PhGaNInv board?
