TransformerLess Power Supply 12V 100mA
This is a transformerless power supply for low current applications. C1 is the X rated AC capacitor that reduces high volt AC. D1-D4 rectifies AC to DC and C2 removes ripples. R1 is the bleeder to remove stored current in AC when power is off. R2 limits inrush current. A Zener can be used in the output to get regulated DC.

Well this is exactly what I was looking for, surprised there are no other comments. Is there a catch to this set up? Heat for example?
ReplyDeleteI would like to make a power supply for 2 Raspberry Pi computers.
rates at 5 volts 1amp each. Will the Zener diode determine the output voltage
Sir I want to know that this will give heat in zener or not because I have made some transformer less power supply in previous and they give a hell lot of heat generated at zener
