What is rectification and rectifier why pn junction diode is used as rectifier?

What is rectifier explain?

A rectifier is a device that converts an oscillating two-directional alternating current (AC) into a single-directional direct current (DC). Rectifiers can take a wide variety of physical forms, from vacuum tube diodes and crystal radio receivers to modern silicon-based designs.

What is diode rectification?

Now we come to the most popular application of the diode: rectification. Simply defined, rectification is the conversion of alternating current (AC) to direct current (DC). This involves a device that only allows one-way flow of electric charge. As we have seen, this is exactly what a semiconductor diode does.

Which is used as rectifier?

We know that the core use of rectifier is to convert AC current into DC current. The rectifier consists of semiconductor diodes to do this function.

Why diode is used in rectifier?

A rectifier is a device that converts an Alternating Current (AC) into a Direct Current (DC) by using one or more contact diodes. … Thus, the diode allows current in forwarding bias conditions and blocks current in reverse bias condition. In simple words, a diode allows current in just one direction.

How is pn junction diode used?

Application of PN Junction Diode

The junction which is the p-n junction diode can be used as a photodiode, the diode which is sensitive to the light when the configuration of the diode is reverse-biased. It can be used as a solar cell. When the diode is forward-biased then it can be used in LED lighting applications.

How a pn junction can be used as a full wave rectifier?

A full wave rectifier is a circuit which converts the entire alternating input voltage into direct voltage. This is achieved by using two junction diodes. The p-sides of the diode are connected to the input while the n-sides are connected together and along with the centre, tap form the output.

How are diodes used in rectification process?

The main application of p-n junction diode is in rectification circuits. These circuits are used to describe the conversion of a.c signals to d.c in power supplies. … The filter smoothes the pulsation in the voltage and to produce d.c voltage, a regulator is used which removes the ripples.

When a diode is used as a rectifier The most important consideration is?

The peak inverse voltage is either the specified maximum voltage that a diode rectifier can block or, alternatively, the maximum that a rectifier needs to block in a given application. When a crystal diode is used as a rectifier, the most important consideration is a PIV rating.
