A bridge rectifier is an array of semiconductor diodes configured as a bridge that acts to change AC (alternating current) to full-wave pulsating DC (direct current). It is used in many electronic devices including laptop computers, cellular phones and PDA's. Depending on how you're viewing the electronic component, the four diodes form a square or diamond pattern. In a single-phase bridge rectifier, there are four diodes; in a 3 phase bridge rectifier, there are six diodes.
When AC current is connected across one diagonal, DC current is available across the other diagonal. The four diodes allow full-wave rectification without the need for a center-tap on the transformer.
Single-phase bridge rectifier is the most frequently-used circuit for electronic dc power supplies. It requires four diodes but the transformer used is not center-tapped and has a maximum voltage of VSM. The full-wave bridge-rectifier is available in three distinct physics forms. The main advantage of this bridge circuit is that it does not require a special centre tapped transformer, thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge network and the load to the other side.
