Are there any IC controllers available for inverter operation (DA/AC converter)?

There are many out there.

All push pull controllers do the job. tl494  uc3825  uc3525 etc.

H, Ali:

Thank you very much for your quick answer.   

 These chips have two interleaved outputs.  For bi-polar PWM inverters, the two gate signals are complimentary, not interleaved.  Are there other choices?

 Thank you.

if you are going to make a single stage inverter with iron transformer, Those chips are fine.

if its a modified sign wave switching type ,you need two stage .one stage to make around 250 dc(or 120v) and one stage to invert this to a modified sign wave with 4 igbts.

for both stages you can use the chips I mentioned.

If you need a true sign, its better a dsp to do all the job including boost stage and sine pwm etc.

if you are familiar with dspic33fj series from microchip,there is a lot of  dsps for switching application.

I know there are some TI chips too, but I am not familiar with!
