I would like to know is it possible to step down 240V Ac from a PSU to like about 12 V Dc without using a transformer.
For eg using a full wave rectifier, zener diode, resistors and capacitors.
For further detail,
I have this project where I wanted to build a remote control socket. There would be a receiver to act as a remote to control the relay. Hence, I do not intend to use any battery supply to run it. I was think to use the PSU supply to run the device, but stepping down the voltage without using a transformer. Is it possible?
