This project aims to develop a versatile 12V 41A bench power supply using two 500-watt Dell server PSUs, acquired for a nominal cost. The design integrates MOSFETs and a buck-boost converter for robust voltageAND current regulation, controlled by a potentiometer. Plans include the incorporation of an Arduino Nano and Digital potentiometer to enable computer-controlled adjustments, enhancing the power supply’s functionality for precise, real-time modifications. This setup will provide independent control of voltage and current, ensuring high efficiency and adaptability for various electrical tasks.
