hi i am currently going a project on ac to dc inverter using igbt as switch. The software used is psim. i have problem getting the output voltage to the value desired. I had attached the circuit for one reference. the spec given is DC voltage of 500 , frequency for ac source is 50hz, carrier()triangle frequency is 1000hz. result wish to obtain is 220V AC output.

I had been thinking of playing with the parameter of the sine and carrier(triangle) to achieve the dead time to get 220V ac output but fail.

Can anyone please help to solve the problems.Thanks in advance.
