dc to dc convertot

I have a variable voltage DC source(42V-48V) and i want a constant 48V output. can i achieve that throug dc to dc convertors??

 

If you have sufficient input power, you might use a buck-boost, SEPIC, or similar topology. You might get by with just a boost topology, but I have a feeling that your input voltage may exceed your desired output voltage.

 

i have a dc power source with 43-48V output. but i want a constant 52V output. will dc to dc converter work for me? and if yes, can someone give me some link for that!! it will be of great help!!

 

How much current do you have available at 43v-48v?

How much current do you need at 52v?

Without the above information, it will be difficult to suggest a suitable circuit.

What is it exactly that you are wanting to do?

It sounds like you want to charge a battery bank. For that you need a charge controller, not a constant voltage.
