Hi all, i'm trying to build a transformerless converter unit, that will take an input of 240v a.c, and will output 12v d.c. I used a voltage divider to get a 16v from the a.c supply of 240v and connected my rectifying circuit across the 16v. I got an output of 14.59v. But on connecting the capacitor, the voltage went up to 22v. WHY? Another thing is that, on connecting the zener diode, i was unable to get any reading. I'm confused.
