yes you can use any kind of rectifier
as you know there are a lot of rectifiers exist
And their categorized by methods that use
Switching or …
You can use switching because this method very use these days
You can find a lot of book and article for this technique on EDABOARD
Have nice days
I don't have the exact circuit right here, but you can google "transformerless power supply". You'll find circuits that produce low voltages directly from the mains with the help of a couple of diodes and a few passives.
hi,
connect about four (105M/J)(250V) FARAD (equivalent to 1 micro fard) capacitor parallel with 57K resistor with each of the 4 parallel circuits in series with each other. i had practically tried this out to light a 12V bulb in my house.
there will be dabger of safety for such high voltage to low voltage conversion directly...
we have to some circuitry to convert 230 V ac to 12 V dc.... which will cost some money... instead , step down transformer can be added.. and can get 12V DC
