Diode is 2 terminal device used in electronic devices. Diode conducts current in one direction and block in other. it is commonly used as rectifier and reverse current flow protection in a circuit. Subset of Diode is Zener diode and it is used for voltage regulation in electronic circuit.
A bridge rectifier is an arrangement of four or more diodes in a bridge circuit configuration which provides the same output polarity for either input polarity. It is used for converting an alternating current (AC) input into a direct current (DC) output. A bridge rectifier provides full-wave rectification from a two-wire AC input, therefore resulting in lower weight and cost when compared to a rectifier with a 3-wire input from a transformer with a center-tapped secondary winding.
