AC Electronic Load Circuit

cooldesire:
Hello all, I'm new here...
Can anyone help me to find a circuit for "ac electronic load"
very important for me, it is my final year project
I have two months to finish it.

plenty of time to design one then i think...

Since it's your final year project YOU need to do the work ...
We can help.. but you need to show what you have found so far, what routes you have explored.
What current range are we talking ? what voltage range ?
What about burden voltage ?

Take a look at how a programmable current load is made. There's plenty of schematics floating around. in its simplest form it is a power transistor , a current sense resistor and an opamp ...

As for the AC problem : here is a hint : convert your AC problem to a DC problem ... and then the solution is easy. ( think of a rectifier )

Its amazing you don't even bother to search at the net instead of asking people here to do it for you for your homework.

Another crappy electronic engineer in making.  ;D

cooldesire:
I tried to simulate a circuit is taken place IEEE paper about "study on ac active load simulator" and worked on over "dc electronic load" for ac operation, but I couldn't succeed... Finally I decided to ask someone and right now I'm here...
project ratings: Minimum 1A(rms)/48V(rms), f:50-60Hz
 need a full schematic, I fail to  design a circuit by myself...
in the attachment, worked on over "dc electronic load" schematic taken place...

It is kind of sad  :o but i do agree with you.
