      Does the NPC inverter works with the control design you used for 3 phase standalone inverter for balanced and unbalanced load?
      Also will you consider making a video on inverter switching design from grid tie to islanding?

    kindly, explain how to calculate the filter values (L&C). You directly put the values so we cann't able to design the inverter for some other ratings. Pls explain the parameter design too. It will be helpful for us.

    Thanks for the video. Very good explanation. Can you please make some videos on Multilevel inverter fed induction motor drive? For example., 5 Level NPC inverter, Cascaded H-Bridge inverter fed Induction motor using vector control or direct torque control. I highly appreciate your work. I have also recommended my students to follow your channel for better understanding of inverter control. Thanks in advance. Go ahead.

    This is very informative & knowledgeable video.
    But, I a doubt on PWM. You considered one carrier is (0 1 0) & other one is (-1 0 -1). It will be very helpful if you share the concept of it with us.
    Thank you.

      Look for the Vienna rectifier, which is a three-level AC to DC converter. Control is different.

  • @ebarbie5016
    @ebarbie5016 3 роки тому +5

    This will not work OK for a practical system with unbalanced grid/load because you neglected to apply voltage balancing to the inverter DC bus. You should feed the Vc1-Vc2 error to a third PI controller and feed the output to the zero vector port of the final dq0 to abc transform...

      yes. DC bus balance can be achieved by modulating a dc current component into the dc junction as in a Vienna rectifier.
