This document describes the operation of a full-wave rectifier circuit that converts alternating current (AC) to direct current (DC) using diodes arranged strategically and a capacitor that stores energy and distributes it continuously. It discusses the components used - including a full-wave rectifier bridge made of four diodes, a step-down transformer, and an electrolytic capacitor. The circuit is designed and simulated using Proteus software, which is used to design the PCB layout and visualize the circuit in 3D. The conclusion is that full-wave rectifier circuits using a bridge of four diodes and simpler transformer can lower costs compared to other rectifier designs.
