How does Rectifier Work?

A rectifier is an electrical device which is used to convert AC current into DC current. Rectifier does this process by allowing current (I) to flow through any device and the process taking place here is called rectification.

Rectifier works by using diodes which are like one-way valves for electricity. A rectifier can take one or more diodes to convert the positive or negative half cycle of the AC inputs DC outputs. Rectifiers generates an DC voltage by rectifying any one cycle of the AC supply and the reverse operation of this above process is called Inverter and the process called inversion in electricity.

Rectifiers Circuits

It plays a vital role in DC power supplies for converting AC signal into DC signal. P-N junction diode have lot of applications and Rectifier circuits are one of them. In simple words the electronic circuit which performs rectification is called rectifier circuit. By using this circuit we can able to convert electrical signals.

Rectifier

Rectifier is an electronic component that converts alternating current (AC) into direct current (DC), ensuring a unidirectional flow of electric charge. As we know, electricity reaches our homes from power grids in the form of AC, but most commonly used electric appliances, such as mobile phones, computers, televisions, fridges, etc operate on direct current (DC). Therefore, the rectifier becomes a very useful component in electronics.

This article provides a detailed understanding of the electrical component known as a rectifier, including its types such as full-wave and half-wave rectifiers, controlled and uncontrolled rectifiers, etc. In addition to that, we will learn about various specific rectifiers such as the Mercury Arc Rectifier, Selenium Rectifier, and Precision Rectifiers.

What are Rectifiers?

Rectifiers are electronic devices or circuits that convert alternating current (AC) into direct current (DC). Alternating current periodically changes direction, whereas direct current flows consistently in one direction. Rectifiers are crucial in many electronic applications where a steady DC voltage is required....

Half Wave Rectifier

It is easy to construct. Similar to rectifier Half way rectifier is used to convert AC (Alternating Current) signal into DC (Direct Current) signal by passing through negative or positive half cycle. The only drawback is it is less efficient by comparing to full-wave rectifier. In simple words Half wave rectifier produces purely positive by avoiding negative half-cycle on the other hand full wave rectifier produces purely negative half cycle by changing the direction. The efficiency of half wave rectifier is 40.5% which is considered as lower than full wave rectifier....

Full Wave Rectifier

It requires multiple diodes to function and to construct. It is a process of converting AC signal into DC signal (AC voltage into DC voltage). As we know that electrical circuits which convert AC into Direct current are called rectifiers. Full wave rectifier rectifies both negative and positive half cycle of input which is alternating signal. The efficiency of full-wave rectifier is twice than that of half-wave rectifier. So these rectifiers are maximum used in all electronic devices because it can withstand high voltages or current with intense power....

Bridge Rectifiers

It is an type of full-wave rectifier which uses four diodes to form a close-loop bridge. It conduct in pairs through each positive and negative half cycle which leads to no power wastage. It is also called rectified output voltage. Rectifiers are mainly used in power supply, providing DC voltage for electronic devices to function. It doesn’t require any center tap over the secondary winding of the transformer ....
