Transformerless Power Suppply

Now it would be a good time to post that schematic here.

BTW; let me remind you that Melanie has a Klingon cloaking device.

Hi sayzer,
well here is the schematic. Im not so good in drawing like U.
I had a fridge which had thermostat gone bust. So I made this ckt and
saved lot of energy 0.75KWHr /day instead of 5KWHr/day. I also found
that most of fridges have improper settings evenif the thermostat is OK and
there is lot of frost and they consume abt 3-4 KWHr/day. So making a
commercial unit costing Rs.400/- ( $9 appx.) have installed in abt 20-30
homes and they are all saving energy down to 1KWHr/day.
The consumption of unit is less than 05VA and there is no area even feeling
warm. I cant afford to use X2 capacitors in this as that will push cost of unit.

Can someone explain to me how the 240VAC after rectification can come down to +12VDC?

Are you kidding me? I have enjoyed the arguments a lot, and from the first post to the third last (subtracting yours & mine of course), I have come across 2 to 4 circuits all making 12VDC. Check them out going back few posts (Remember to use X2 capacitors with mains - else Melanie would not like it - in case she comes across your circuit )
