    Dear

    Please answer this question, I found it as an MCQ:

    What is the output waveform of Three Phase inverter connected in Star connection and conduction angle is 120 degrees?

    Different options were square wave, quasi square wave, six step square wave etc?

    Thanks

    The same as three single-phase inverters with a 120-degree shift from one to the next.

    would it be six step square wave?

    In the case in which large harmonic content is ok, yes. Or it could be a 360 step sine wave, or...

    If that's what you want for each phase.

    The waveforms will be whatever you chose to make them. The three phase definition just means that there will be three of them with a 120-degree timing separation between them.

    Methinks your title of 'electronic engineer' does not fit your knowledge base. :rolleyes:

    I have been untouch with all such things for a very long time and now need to revise the basics
