I use 1500W for P(out) . 90% for Efficiency . and 50V for Vin . and the result is 33A .
 

Hi
How you calculated 33 A ? ( my mean is what is your formula ? can you show me , the steps of your design? thus i or the others can correct them .

Dear ronish
Hi
At first , it think you'd better to create new thread .
Anywhere , if you want linear regulators , try LDO what is good for your aim .
