Make voltage and current Adjustable Power supply, DC voltage controller DIY

Make voltage and current Adjustable Power supply, DC voltage controller DIY.

This is a voltage and current Adjustable Power supply using TIP3055, LM317, and BD139 transistors. This is a basic voltage and current adjustable power supply. But not a powerful DC voltage controller. You can supply an input maximum of 12V to 20V, 5A - 10A.

An adjustable DC power supply is capable of delivering a variable output voltage or current. These adjustable power supplies fall into three categories: locally adjustable power supplies, remotely adjustable power supplies, and programmable power supplies.

Components used in this project:–

1. TIP3055
2. BD139
3. LM317 or LM337
4. 10k Potentiometer x2
5. 220 Ohm 2W
6. 22 Ohm 1W
7. 1N4007 Diode
8. Voltage and current Digital meter
