is there a particular reason why this driver, being an opto-coupled driver
is a advantage here, given only low voltages are in that part of the circuit?
but a direct driver can do much better.......

by the way U must to use full-bridge topology like andre_teprom says
for this purpose U're better to Use ir2110 or 2113 as MOSFET driver just use it's datasheet schematic
note: never use this IC for PWM it just support low frequency like 50 or 60 hz

First of all, use SG3525 to generate pulses at 50kHz. Drive power MOSFETs with this and feed into ferrite transformer. Check the waveforms and add snubbers if necessary. After the voltage is stepped up, use rectifiers and caps to convert to clean DC. Then have another SG3525 and ir2110 running to drive an H-bridge at 50Hz. You should sear

Hi FvM, sorry for the confusion.
here is post #4 and #10 we combined it actually.
The transistor inputs are SQUARE WAVES. The H-bridge creates an AC voltage due to alternate switching of the transistors as we have programmed.
since u mentioned that there was something wrong w/ the circuit on post #10 this is how we actually made it.

Your explanantion doesn't correspond to the circuit diagram, which shows a common ground of IR2210 logic side and DC bus. Actually, ir2110 would never work with a floating ground.

But as I know ir2110 maintain sufficient dead time this should not be the problem as the inverter runs sometimes fine.
ir2110 only assures delay matching better than 20 ns but doesn't care about dead times.

Basic Requirement for design as as follows:
Consider the DC voltage of operation. Say For example 12V, The peak voltage that can be availabe across the mosfets is 30V, so safely consider a mosfet of 50V Vds. remenber that Lower the Vds better is the Rds and hence the losses in the MOSFET.

For sine wave inverter with 110VAC output, you need an input DC voltage of 170V. If you cannot obtain this and are limited to 110VDC, you will need a DC-DC converter to step up the 110VDC to 170VDC.
Next comes the H-Bridge / Full- bridge whichever you call it. This will consist of 4(or more in parallel) MOSFETs / IGBTs driven by
