  1. Welcome to this tutorial on designing a variable power supply with adjustable voltage and current using LM317 IC, BD139 and TP3055 transistors. In this tutorial, I will walk you through the steps involved in designing this circuit, including the schematic diagram and the necessary components.

  2. Build a Variable Lab Bench Power Supply: Working on electronic projects at the workbench, whether prototyping with a circuit, powering a small desktop device, or simply testing a component, all require a specified source of power.

  3. That's why every DIY maker must have their own bench power supply. Now I'm going to show you how to build an awesome variable bench power supply. So take your tools and let's get started :)

  4. 6 lis 2023 · In this post I will elaborately explain how to build a simple LM317 based adjustable power supply circuit using minimum number of external components. As the name suggests a variable power supply circuit provides the user with a range of linearly varying output voltages through a manually controlled potentiometer rotation.

  5. Continuing on from our tutorial about converting an ATX PSU to a bench power supply, one very good addition to this is the LM317T positive voltage regulator which we can use to create a variable voltage power supply.

  6. Learn about the 0-30V variable power supply circuit diagram and how to build your own adjustable power supply for electronics projects.

  7. 29 lut 2024 · With this homemade variable Power Supply unit, you can set a specific voltage (0-36V) and current limit (0-5A) for that circuit you want to power. The device even has some common fixed voltage outputs at the front as well.
