   For my next project I have acquired a transformer with two identical 450v   
   secondary windings.  I could put the windings in parallel and use a bridge   
   rectifier.  Or, I could put the windings in series and ground the coupling   
   for a 450-0-450 configuration to use with a pair of diodes.   
      
      
   If you choose parallel connected secondary windings, a power meter test is   
   one way to be sure.  Fire up the transformer and measure the input power   
   (primary) with the secondary windings not connected.  Repeat the test with   
   the secondary windings connected in parallel.  If the windings are   
   identical, the primary power will not change.
