TINA/Spice: phase shifted full bridge ucc28950 and three phase rectifier at the input

Tool/software:TINA-TI or Spice Models

hello

I have prepared a simulation as described in title thread. the analysis parameter settings i kept as given in reference design for 28950. now the steady state is expected to achieve after 0.75 sec.

i have ran the simulation for half hour its not even 1%. so how should i modify the parameter settings to simulate it properly but also to reduce the huge time its taking?

any references?

thanks
