AC to AC (100-270)VAC to (120-240)VAC conversion

[sivamit]

Hi friends,
I have a requirement where I want to convert (100-270)VAC to (120-240)VAC (a cheap circuit version is also okay). I have ,so far, handled only a simple transformers to step up or step down AC voltage. Could you suggest any solution for the above ? :shock:
The output AC voltage does not have to be linearly varying with the input. I just need a voltage output within the range. i.e
For input 100-270 if 120<Output Voltage <240 then our circuit works. 8-O

Thanks for your time..!!! :-D


Regards,
Sharon;-)

Hi Kak111,
Thanks for the info. I will see if I can understand the circuit.

Hi Kak111,
The circuit seems to be okay with simulation.
