The bridge rectifier is an electronic component that is widely used to provide full wave rectification and it is possibly the most widely used circuit for this application.

Using four diodes the bridge rectifier the circuit has a distinctive format with the circuit diagram based on a square with one diode on each leg.

In view of its performance and capabilities, the full wave bridge rectifier is used in many linear power supplies, switch mode power supplies and other electronic circuits where rectification is needed.
