220v To 5v Power Supply Circuit Without Transformer

Resistor r1 does the job of current limiting and bridge d1 rectifies the mains voltage.

220v to 5v power supply circuit without transformer.

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. It works by using a high voltage capacitor to drop the mains ac current to the required lower level which may be suitable for the connected electronic circuit or load. 220 volt to 12 volt dc power supply without. The purpose of the post is to provide four transformerless power supply circuits and start the discussion.

Low voltage dc like 5v 6v 9v 12v is used in electronics circuits led bulbs toys and many household electronics items generally batteries are used to power them but they need to be replaced time to time which is not cost effective and also takes our time energy. In this project we will design transformerless power supply for low current applications. Even if you try to build a traditional dc power supply with transformer the input is still high voltage ac 110. The working of this circuit is quite simple.

Basically a transformerless power supply is just a voltage divider network that takes the 220v ac as input and divides it down to lower dc voltage that we want. Instead of discussing how and why the circuits work some readers focus on the dangerous side of the circuits that involve ac. Generating low voltage dc from the 220v or 110v ac mains is very useful and necessary in the field of electronics. Here is the circuit diagram of a 5v transformer less power supply using minimum components.
