    Hi all,i'm confused with the 2 level 1 leg inverter.
    Assuming a one leg 2 switch inverter is supplied with a capacitor at a voltage of E like the picture here:
    i got a waveform switching between E and 0.However,i see some papers having this configuration
    which the waveform varies from 0.5E and -0.5E i think.
    My question how does these two differ in their application in single and three phase systems?
