4 Simple Transformerless Power Supply Circuits Explained Homemade Circuit Projects
Capacitive power supply with more power efficiency. An efficient power supply that can deliver 9V DC at 100 mA is shown in Fig. 8. 230V AC is stepped down to 24V AC by capacitor C1. This low-voltage AC is rectified by a bridge rectifier to give 20V DC. Capacitors C2, C3 and C4 eliminate ripples from the DC and store current to stabilise the output.
Transformerless power supply regulated 220v5v Electroinvention
For more understanding I designed these two circuits, one for the above calculations (12v 500mA) and other one for 60v(12mA) as a 7W LED driver. You can see all the design consideration here in the circuit diagram. The problem comes in transformer less power supply when we need huge current like to drive some kind of inductive relay system.

Definition: A transformerless power supply converts high AC input voltage ( 120V or 230V) to the desired output DC low voltage ( 3V or 5V or 12V) with low current output in milliamps. It is used in low power electronic applications like LED bulbs, toys, and household appliances. It is cost-effective, and need less space.
Simple 12V 3A Power Supply Circuit
Voutput = 12V - 0.6V = 11.4V. Power dissipated by the diode = VI = minimal. The 1N4004 that can handled a RMS reverse voltage of 280V selected is a good selection. 7) Maximum power dissipated by zener diode without load = VI = 12 * 0.0146 W = 0.1752W. So 1/2W or up is good. 8) The specifications selected for the smoothing electrolytic.
