Application of Rectifiers

The main application of rectifiers is to derive DC power from AC power. These are used in the power supplies of all types of electronic equipment. In power supplies, the rectifier is generally placed in series following the transformer, smoothing filter, and voltage regulator.

  • Used in Powering Appliances: All electrical appliances use a DC power supply to function. By using a rectifier it helps in converting AC to DC power supply. Bridge rectifiers are used for large appliances which are capable of converting AC voltage to low DC voltage.
  • Used With Transformers: With the help of a half-wave rectifier, it can help to achieve the required DC voltage by using a step-up and step-down transformer. The full wave rectifiers are used for powering the motor and LED which work on DC voltage.
  • Used in soldering: A half wave rectifier is also used in soldering iron and also used in mosquito repellent to drive the lead for the fumes. In welding which is done with the help of electricity, the bridge rectifier is used to supply steady and polarized voltage.

Types of Rectifier

A Rectifier is an electronic device that converts the alternating current (AC) into direct current (DC) by allowing a current to flow through the device in one direction only using one or more P-N junction diodes. Many circuits use DC voltage for operation. It can easily convert AC voltage or current into DC or voltage. A P-N junction diode allows the current to flow in a forward bias condition and blocks the current in a reverse bias condition. More simply we can say that a diode allows electric current to flow in a single direction. This property of the diode allows it to act as a rectifier and the process is called rectification.
