Power supply circuit diagram

The 12v Transformerless Power Supply is alternative to series resistor for voltage dropping, utilizing series capacitor and bridge rectifier.

This is the LED light power supply for a 5-watt LED light. this circuit can make 5 watts. here 4 diodes to make AC to DC voltage

A Boost Converter takes an input voltage and boosts it. In other words, its like a step up transformer i.e it step up the level of DC voltage (while transformer step up / down the level of AC voltage) from low to high while decreases the current from high to low while the supplied power is same. Working and Circuit diagram of a boost converter

So here in this article, you will learn to design your own variable current and voltage 10A laboratory power supply circuit. Features

In this post I have explained many different transformerless power supply circuits using a PPC capacitor, zener diode, transistor, SCR, IC MOC3010.
