Power Electronics
The Breadboard Power Supply (BBPS) is designed to provide regulated power to your breadboard projects at either 3.3V or 5V. It accepts input power through a DC barrel jack or via stripped wires on secondary input terminals. The BBPS can handle input voltages ranging from 6V to 30V DC from a DC wall adapter and outputs a steady 5V or 3.3V, selectable using a convenient slide switch.

Almost all electronic devices and instruments rely on a DC power source, which can be a battery or a power supply. These devices require not only DC voltage but also a filtered and regulated voltage. While there are various types of power supplies, this project focuses on designing and constructing a linear power supply. The goal is to design, build, and simulate a Dual-Polarity-Variable Linear Power Supply featuring an external 5-Volt USB port, fixed ±12V outputs, and a variable output ranging from 1.25V to 10V with a maximum current of 1A. The circuit board for this project is designed using Eagle CAD software.
There are many different switching voltage regulator topologies, such as buck, boost, buck-boost, and Cuk. However, this project focuses solely on the design and construction of a boost converter. This converter can increase a 12V input voltage to a variable output voltage ranging from 12V to 24V, controlled by a potentiometer. The boost converter achieves this by storing electrical energy in an inductor and then releasing it to the load at a higher voltage level.
