hi,
i want to make a buck converter whose input voltage is 220v dc and i require 180 v dc almost 82% duty cycle.
help me out with different topologies which r suitable to use
 

Dear sasidhar
Hi
How much current do you need ? you forgot to mention it . as tahmid said it is simple to do . if your required current isn't high a mosfet can be used as power switch but if the current is high , IGBT would be better .
Best Wishes
