Hi! The attached file is a schematic of 50 Hz H-Bridge which I want to use in the final stage of an inverter. In this respect please help me either any modification in the circuit is required? the power of inverter is 500 Watts.

Where are you getting the 240v dc ??

yeah, especially to be able to supply 3-4 amps, thats a lot of power...

What would be the load?
What's the driving signal? Square or sine?
With such power you may want to consider to calculate dissipation on both bridge and load.
