yes, I used a square wave, so my output voltage swings from +DCLINK to - DC LINK.
On the example above, the input was 10V, and the line to line voltage is 20V.
BTW, this is nothing new, thats how cheap square wave inverters (12 to 110 or 230V) work. A switch mode power supply boosts the 12V to 320 (the image is wrong, Vpeak is 340V!!) and then a mosfet bridge just inverts the polarity of the output with a dead time in between (quasi sinusoidal output). I just never remembered I could use the same technique on a motor inverter until this morning
