i want to build variable switching power supply with:
vout=0--50 volt
Iout=0--10 amp
any one can help me to build this circuit
 

there are many types of smps: flyback, forward, buck boost, etc...

designing an smps is not as easy as designing a linear power supply.

i recommend you read a book by Pressman, it's all about smps. Sorry i forgot the title.
 

My suggeston is to first step volage down to, say, 50Vac (using a step-down transformer) and then build a dc/dc smps 0-50V, 0-10A.
See this example:

The best circuit for this job would be a full-bridge, taking into account the power level. The control loop (or loops, one for voltage, one for current) can be implemented similar to linear power supplies. You can PM me for details.

I would like to emphasize though that I do not recommend you undertake such a project, unless you have experience with building SMPS, especially SMPS transformers.
