How To Build A Bench Power Supply (DIY Project Download)

how to build a bench power supply 1

Make sure this wire is connected to the other orange wires, otherwise your lab power supply won’t stay on.) This wire should be connected to either an orange wire (+3. I considered buying a bench power supply. But prices were too high, especially for ones with adjustable voltages. So I decided to build my own. This one has 4 outputs. Hobbyist electronics projects need robust, reliable power supplies for prototyping and testing. I learned how to build this circuit from the Basic Analog C.

how to build a bench power supply 2The circuit incorporates some unique features which make it quite different from other power supplies of its class. Instead of using a variable feedback arrangement to control the output voltage, our circuit uses a constant gain amplifier to provide the reference voltage necessary for its stable operation. DIY is always my preference. However, while reading articles and blog posts, I noticed that single or multi-channel variable power supplies seem to be common on serious designer’s workbenches. A proper electronically stabilized bench power supply unit is an important but also expensive device. Using a microcontroller based design we can build a power supply which has a lot of extra features, is easy to build and very affordable.

Another thing everybody needs (and has probably built) is a simple laboratory bench power supply. A lot of people use things like modified PC power supplies but I wasn t in favor of this because I wanted something smaller, lower current, and cleaner (from an RF perspective). I’m looking for a good tutorial on building a bench variable power supply. Most of the stuff I’ve found online hasn’t been that helpful. And I don’t want to make one from an old computer PSU. Limpkin has published a new build: a high voltage power supply for Nixie tubes For quite a while I’ve had this project idea in the back of my head that would involve using many Nixie tubes.

Every bench needs a power supply to fully complement the rest of its test equipment. DYI Links. Here are some articles detailing modification of an ATX supply to be a bench supply.
