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 many different transformerless power supply circuits using a PPC capacitor, zener diode, transistor, SCR, IC MOC3010.

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

About this item Build an AC/DC Triple Output Power Supply, useful anywhere precise DC voltage is required Features three fully regulated solid-state power supplies Ideal for use in school labs Made in the United States For 30 years Elenco has been using their strong engineering and design skills to develop reliable, affordable electronic test equipment, tools, and educational kits

The high power adjustable switching power supply is perfect for the purpose of laboratory work. The topology used to design the system is switching topology – half controlled bridge. Written and Submitted by: Dhrubajyoti Biswas Warning: The following circuit design works with a direct 220 V Mains AC without any isolation at the input side, […]

I have always believed that one of the best things about being a maker, is the...
