DC Variable Power Source

Overview This project consists of the design and implementation of a variable DC power supply. The system provides an output voltage ranging from 0 V to 20 V. The circuit was simulated in Proteus, fabricated on a custom PCB. Variable voltage output: 0 V to 20 V LM317 regulator Full-wave bridge rectifier and smoothing capacitors Manual adjustment via potentiometer Integrated voltmeter display Validated output stability under varying load conditions Tools and Components Simulation: Proteus Fabrication: PCBWay Gallery
