Project Overview
This project involved the design and fabrication of a regulated DC bench power supply for laboratory and prototyping use. The supply provided adjustable voltage (0-15V) and current (0-3A) outputs with less than 1% load regulation. The design emphasized safety, reliability, and usability, making it suitable for powering sensors, microcontrollers, and small electromechanical systems during development and testing.
My Contributions
-
I designed the electrical circuit, selected key components such as the transformer, rectifier, and voltage regulators, and assembled the system on a perf board. I integrated an LCD display for monitoring voltage and current in real time and added modular banana plug outputs for flexible use. I also tested the supply with oscilloscopes and multimeters to verify stability and load response.
