    I have followed the video titled “3 phase grid link inverter with dq control complete design | PSIM” but my Ia, Ib and Ic simulated results look very different from that in the video. I have checked my circuit but there seems to be nothing wrong. Any help is appreciated thanks.

    Time step is too big, you only have 10 points per cycle, which is the ABSOLUTE minimum, 50-100 points per cycle will give you better resolution.
