Dear xmen
Hi
I think you forgot to attach your schematic ! what kind of current limiter ? DC ? AC ? how much is the voltage range ?

What? Did you post in the wrong thread by mistake? Why did you put a copy of Shaq's buffer circuit next to an oscillator circuit?you can make a PWM oscillator which acts is not an active device but It will restrict the current.
I Think that u didn't get what i say ,
First i went to circuit diagram to limit the current by 1.8A with 12v
second i went to know " if i have a device , it draw 12v, 3.2A
by using this circuit it will draw 12v,1.8a ? "
But i'm i was wondering that how can i set this circuit to achieve D.C around 0 up to 100 percent without any variation in frequency . your circuit has not any variation in frequency but it's D.C is restricted to the special range .
Hi again karthick
What are those inductors in your circuit ? and about what i have seen , i have simulated your circuit in Ps pice , and it's duty cycle couldn't change from zero up to 100 . can you show me your simulations , please ? perhaps my simulation was not correct ?
Regards

I dont have the simulation with me. I tried the simulation yesterday and my windows crashed ! Anyway I have made it up and checked it on the scope a few times. But I might try and build it up again and check. I will let you know soon.
