Power supply design

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.

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

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

Most problems with equipment using switch mode power supply (s.m.p.s) like television and monitor are power related, this is because power supplies runs under considerable stress due to high voltages and current involved around these circuits. In order to understand how to solve s.m.p.s problem I am going to show you how to analyze common failure mode in CRT television, you can use this principle in repairing CRT monitor too. Case One: CRT Television Dead Here dead I mean the set does not…

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

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