Hi,
I am trying to convert 40V rms ac to about 35V using zener clipper circuit, please let me know if this will work.

Thanks

 

I don't think that is a good idea, because the R1 is too small and the VR1 will also small, the voltage cross on the zener diode will be close to V1, it could kill the zener diodes.

You better using the normal method to get the power, something like full wave rectifier and adding bjt and zener or using LM317 to do the job.

 

Too many years ago to find it now. I saw this circuit done with an LM317 and an LM337 to do a bipolar clipper. If you're good at this, that's all the information you need to duplicate the circuit.

 

What you have is kind of like a shunt regulator.
You could put the rectifier diode first, then only one zener to clip the positive peaks.
Since your source has a resistance of 10 ohms, what is the purpose of the .22 ohm resistor.
After all that BS from me. The zener is only a one watt one, so check the power in it with spice.
You don't show a load nor specify how much current you need from the circuit. This is often a problem with shunt regulators.

 

Thanks for your responses.

 

So you want to ignore this thread, otherwise, how come there is no any useful response?
How is the next step?
