It is possible to use UCC2895 as the controller for your application. You need to decide on the driver circuit for the full-bridge. A lot of problems can pop up while designing. This will depend on your previous experience and your skill in designing SMPS circuits. Is this the first time you are making an SMPS circuit? If yes, then, you should start with a small power level, like 50-100W, learning, understanding, testing, debugging and perfecting every part before you move on to make it 3kW.
Hope this helps.

Dear bayya
Hi
I'm agree with Tahmid . a simple float driver , will be ok for your purpose. the transformer driver , will have some problem , and you should add some components , to improve , that. but a float driver , is ok and it's behavior is linear ( transformer , as a driver , can become , nonlinear ).

Since you're using full-bridge, you don't need the balancing capacitor.
A high-low side driver would give you a lot of accuracy, probably more accurate than a gate drive transformer.
Yes, the capacitor improves the circuit. But like we both said, we've seen circuits without it. You'll probably be able to build a good circuit without it.
Hello Sir..
I M in final year electrical..and i m making a project on full bridge converter using microcontroller..
can u sujest me idea about this..

Is the microcontroller going to be doing the PWM? Or is it going to control the PWM chip? --- This you have to decide. If you don't have any idea about this, you need to research about PWM, common PWM chips (like TL494, SG3524, SG3525, etc), their functions and uses. You then need to research on advantages/disadvantages of using the microcontroller instead of the PWM chip. Then, you need to take the decision.
You also need to provide us the specifications like output voltage and current, how far you have studied/worked on this and what kind of help you require.
