Component List

  1. C1 = 225K/400V
  2. R1 = 470K/1W
  3. R2 = 100/1W
  4. Bridge Diode or 4 x IN4007
  5. C2 = 470uF/100V
  6. R3 = 220/1W
  7. ZD = 15V/1W
  8. LED
  9. R4 = 1K
Description

Electronic circuit like in figure 1 above is TransformerLess Power Supply 12V 100mA using Based on Zener Diode circuit. From this circuit, we can build TransformerLess Power Supply 12V 100mA using Based on Zener Diode easily.

According Electroschematics site that published this circuit describe that 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.
