“Power supplies are one of the most popular topics in electronics. There are two major types of regulated power supply: linear and switching. Both power supply types introduce some advantages and disadvantages, however, a linear power supply offers better line and load regulation figures and it handles lower noise at the output, specifically when the power supply is adjustable and the output is under load; although its efficiency is lower than a switching power supply. In this article/video, I introduced an adjustable 30V-4A linear power supply that provides constant voltage and constant current adjustment. The output noise of the power supply is low and has measured using the power analysis feature of the Siglent SDS2102X Plus oscilloscope. All component packages are through-hole, so you don’t need any special tool for soldering. Let’s get started!”
