Variable Step-Up Chopper

Link to this post 30 Jan 15


I have got 12V DC supply but my application needs me to vary voltage from 12V to 48V in small steps of less than 1V. The power rating required is around 1KW. Can anyone please suggest me what device could be used.
I think Step Up chopper with PWM trigger may be used. Please tell if it is possible or not.?

Dear Alok,
Obviously if you have to step up 12V to 48V you can use Step up chopper or try with Forward converter. For forward converter you can use transformer ratio as secondary greater than primary to desired value. If you need 1KW=1000V then you need atleast 12V/125A supply.

Sorry there is small mistake in previous post 1KW=1000W.
