Hi Naim, I recommend using 500 ohm as this is the first time you are running the board. Please run at similar conditions as stated in design design and validate the hardware is good enough. From the first image, in without PWM case, your guiIrms1/2/3 are NOT closer while guiVrms1/2/3 is good, this needs to be debugged first. Then move to with PWM scenario. Below can be tried on the setup: 1. Please double check the current sensing circuitry if any changes been made? 2. Swaping your AC signal (RYB to RBY) to check if the distortion is moved onto different phase? 3. Can you confirm you didnt connect AC neutral to VBUS mid point? 4. are you using the 3phase 3 wire system here or not? Let me know your observations to debug further. Best Regards, Uttam Reddy
