This article describes the transformerless power supply with 12v. If a circuit requires very low current of a few milliamperes transformerless power supply is an ideal solution. The transformerless power supply concept. Transformerless power supply circuit diagram.

Many times we want a simple power supply to operate our low power electronics or electronic circuits. This 12 volts transformerless power supply take advantage of the fact that a zener diode is also a normal diode that conducts current in the forward. I m using the hlk pm01 power supply for a switching circuit with arduino uno like lamps low power consuption circuits tv s routers etc and i need this circuit to be smaller. Before designing a transformerless power supply some facts about ac dropping through a capacitor or resistor are to be considered.

The circuit diagram of this power supply is shown below. The actual value of current given in table i will not be available at the output since it may vary slightly depending on the input voltage and current. As the name defines a transformerless power supply circuit provides a low dc from the mains high voltage ac without using any form of transformer or inductor. Transformerless power supplies are very.

What is a transformerless power supply. I want to try the transformerlees power supply but i need 5 v 600 ma output with 100 240 v input. Voltage drop in the mains severely affects the output current in a transformerless power supply. Y ou can change zener diode and change the voltage if you need 12 volt output use 12 volt zener diode instead 5 volt.

The components of the power supply will also consume some current. In the circuit diagram are not labeled the parts c1 c2 d1 d2.
