What is the rectifier diode?

A rectifier diode is a two-lead semiconductor that allows current to pass in only one direction. Generally, P-N junction Diode is formed by joining together n-type and p-type semiconductor materials. (Source: ©YouraPechkin - stock.adobe.com)

Why we use diode as a rectifier?

An ideal p-n junction diode has zero resistance in forward direction and infinite resistance in reverse bias. This can be used to eliminate the negative cycles in an AC voltage waveform and allow only the positive cycles. This process is called rectification and is useful in many applications like AC to DC conversion.

Which diode is used for rectification?

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. Diode rectifier gives an alternating voltage which pulsates in accordance with time.

What is the difference between a diode and a rectifier?

A diode is an electronic component that allows the current to flow in only one direction. It is a two-terminal semiconductor device. The rectifier is a device that is used to convert an AC voltage to a DC voltage. A diode is used as a switch and a rectifier is used for the conversion of an AC voltage to a DC voltage.

How does a rectifier work?

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.

How PN junction diode act as a rectifier?

The P-N Rectifying Junction

The P-N junction is a rectifier diode because it has asymmetric current/voltage characteristics, allowing the current to flow in only one direction. An example is the conversion of an alternating current into a direct current.

Which is the best rectifier?

For power levels of more than 10KW, three phase bridge rectifier is used because of its simple circuit and less ripple voltage. Also 12 pulse three phase rectifier is the best for high voltage applications because the ripple voltage is very less and it reduces the cost of HV capacitors used for filtering.

What are the components of rectifier?

There are three major components in a rectifier: transformer, stack, and cabinet. The purpose of the transformer is to safely separate the incoming AC voltage (primary side) from the secondary side, which is adjusted to control the output voltage of the rectifier.

What is rectifier filter?

The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage. AdvertisementThe filter circuit can be constructed by the combination of components like capacitors, resistors, and inductors.
