Power supply design

Variable Power Supply 0-30V_10A using dual 2N3055 transistors, LM317, BD139, A/V Meter and two Potentiometers to control amperes & volts.

Learn how to design Linear DC Power Supplies to convert AC voltage into positive or negative regulated DC voltage. We'll see how linear supplies differ from switching supplies, we'll learn how to use voltage regulators, and we will build a nice power supply for our workshop.

In this post I have explained 4 easy to build, compact simple transformerless power supply circuits. All the circuits presented here are built using capacitive reactance theory for stepping down

How to make a fixed voltage regulator? it's an easy circuit diagram to make this circuit. we can use 100 voltage input.
