Thanks but what I want to actually know is if the dead time which I know avoid shoot through in hbridges is also responsible for allowing the leakage inductance to work well as opposed to no dead time in ordinary square wave inverters. What I mean is after the positive cycle pulsing and the dead time is effect, is this when the inductance/capacitor effect takes over judging from what I read about how inductors operate. Hope my question is clear?Using the leakage inductance will be the same as having an inductor in series with the output. As the reactance of an inductor is proportional to frequency it will filter out the harmonics more than the fundamental. If you then add a capacitor in series with the inductor which resonates at the fundamental frequency the series tuned circuit formed will have a very low impedance at the fundamental frequency.

Yes am talking about the one that has the "0 volts" time. Its usually a 50/60hz trafo pulsed at maybe 6-8khz then with a cap at the output filters it.There are too many type of inverters.
I think one type you talk about uses a 60hz transformer and just sends square waves through. No dead time. +110 volts or -110 volts.
There is another type that sends out 160 volts to make the peak right (also -160V) but also has a "0 volts" time so the average (RMS) works out to 110V. Is this the second type you are talking about?
There is another type that used a 100khz transformer. It uses high frequencies. If it had a 200 volt supply then 50% on/50% off will (after the filter) give you 100 volts. (25/75% will give you 50 volts) Here the 25 in "on time" and the 75% is dead time) By changing the on/dead time you can make a good sign wave. Usually has a micro controller. Is this the one you are talking about?
