How many diodes are used in a Full Wave Bridge Rectifier?

A Full Wave Bridge Rectifier employs four diodes to effectively convert alternating current (AC) into direct current (DC). This configuration utilizes the diodes in pairs to allow current to pass through in both halves of the AC waveform. During the positive cycle of the input AC signal, two of the diodes conduct, allowing current to flow through the load. Conversely, during the negative cycle, the other two diodes become active, maintaining continuous current flow in the same direction through the load. This arrangement not only provides a full-wave rectification of the AC signal but also maximizes efficiency and minimizes ripple voltage compared to half-wave rectifiers, which use fewer diodes. The presence of all four diodes and their integration into the circuit design are essential for achieving full-wave rectification characteristics.
