What are bridge rectifier diodes?

Bridge rectifier dioides are specially designed discrete semiconductor devices possessing only one diode as a semiconductor. They differ significantly from the integrated circuit, or IC, semiconductors which typically possess multiple devices. Bride rectifiers are primarily used to convert or rectify an AC into a DC.

Bridge rectifiers can be categorised into different types, such as:

• Single-phase bridge rectifiers
• Three-phase bridge rectifiers
• Full-controlled bridge rectifiers
• Half-controlled bridge rectifiers
• Uncontrolled bridge rectifiers

They are available in different types of packages as well, based on mounting types like through-hole mount, surface mount and screw mount. 

How do bridge rectifiers work?

Invented back in 1895, bridge rectifiers are composed of diodes arranged in a particular configuration. They work with an AC input consisting of two wires and convert an AC input into a DC output, keeping the output polarity the same for either input polarity. Bridge rectifiers provide full wave rectification as well through the specialised diode drops in their design.

Where are bridge rectifiers used?

Bridge rectifiers have common applications across power supplies where DC voltage is provided. As such, they have extensive use in electronic components, devices and circuit construction. Bridge rectifiers are widely used in home appliances, white merchandise, power supply systems, and so on.
