A simple and locally adjustable power supply uses a potentiometer or other voltage regulating devices to adjust the voltage or current at the output. This post explains the working of a variable DC power supply circuit that has an adjustable voltage range of 1.2V to 24V and current up to 5A.
A variable regulated power supply, also called a variable bench power supply, is one where you can continuously adjust the output voltage to you requirements. Varying the output of the power supply is the recommended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide.
AIM: design variable regulated power supply from 1V to 25 V @ 1A We shall follow same procedure followed in Regulated Power Supply. Design of Regulated section:- Step 1: Selecting regulator chip: Because here we need variable supply we shall use LM317. The equation for output voltage is Vo = 1.25 (1 + R2 / R1) In above equation R1 is fixed as 240?.
Control flexibility A variable power supply must have separate controls for voltage and current. Additionally, the voltage control should be independent of fine-tuning or multi-turn. Moreover, the controls should allow you to set the output voltage as you wish.

Yes, a variable power supply can be used to charge batteries, but you must ensure that the voltage and current settings are appropriate for the specific battery chemistry and capacity. How do I choose the right variable power supply for my application?
