you mean just making X mirror will make the center tap as output?
how X mirror will tell the proteus that this center belong the primary or secondary ?
this is the major problem
ya I know that it has center tapped but as secondary, not primary
if I flipped the transformer (x - mirror) what will tell the proteus which terminal are primary and which is secondary then ?
Are you somehow using all three terminals of the center-tapped primary at the same time?
If not then you just need a single primary winding for the simulation.

In a different simulator I created the same inverter concept, and got it working.
The transformer has 2 adjustable specs: (a) primary inductance, and (b) turns ratio.
I used 3H, and .16. It is backwards as you can see. However it appears to work.
I think it is because dynamics in the secondary have an effect on the primary. Therefore the simulator works backwards, in a sense, to reach convergence.
A transformer model has no "direction". The coupling between windings is basically bidirectional. With a real transformer, the only significance of primary versus secondary is an add-on of 5 to 10 percent for the secondary winding to compensate for voltage drop at full load. When using a regular mains transformer "backwards" for a step-up converter, you need to consider this add-on.
