    Circuit number 1 is the correct way.
    The full bridge rectifier converts AC to DC.

    ... and you need AC as input to the transformer to work correctly. The transformer will not operate on rectified AC. It will saturate and look loke a short circuit to the AC mains, thus blowing the mains fuse (at best).
