Rectifier explained

Rectifiers are mainly classified into three types namely half-wave, full-wave, and bridge rectifier. The main function of all these rectifiers is the same as the conversion of current but they not efficiently convert the current from AC to DC. The center tapped full wave rectifier as well as bridge rectifier converts efficiently. A bridge rectifier circuit is a common part of the electronic power supplies.

A rectifier is an electrical device composed of one or more diodes that converts alternating current AC to direct current DC.

A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification. A rectifier can take the shape of several different physical forms such as solid-state diodes, vacuum tube diodes, mercury arc valves, silicon-controlled rectifiers and various other silicon-based semiconductor switches.

A rectifier is an electrical device that converts AC to DC. AC regularly reverses direction, while DC flows in one direction only. Rectification produces a type of DC that encompasses active voltages and currents, which are then adjusted into a type of constant voltage DC, although this varies depending on the current's end use.

The current is allowed to flow uninterrupted in one direction, and no current is allowed to flow in the opposite direction. Almost all rectifiers contain more than one diode in particular arrangements. A rectifier also has different waveforms, such as:. One of the key problems with rectifiers is that AC power has peaks and lows, which may not produce a constant DC voltage. Usually a smoothing circuit or filter needs to be coupled with the power rectifier to produce a smooth DC current.

Best of Techopedia weekly. News and Special Offers occasional. Techopedia Explains Rectifier. What Does Rectifier Mean? Rectifiers are used in various devices, including: DC power supplies Radio signals or detectors A source of power instead of generating current High-voltage direct current power transmission systems Several household appliances use power rectifiers to create power, like notebooks or laptops, video game systems and televisions.

A rectifier also has different waveforms, such as: Half Wave: Either the positive or negative wave is passed through and the other wave is blocked. It is not efficient because only half of the input wave form reaches the output. Full Wave: Reverses the negative part of the AC wave form and combines it with the positive Single-Phase AC: Two diodes can form a full-wave rectifier if the transformer is center-tapped.

Four diodes arranged in a bridge are needed if there is no center-tap. Three-Phase AC: Generally uses three pairs of diodes One of the key problems with rectifiers is that AC power has peaks and lows, which may not produce a constant DC voltage. Share this Term.

Rectifiers

A rectifier is a device which converts sinusoidal AC alternating current voltage into pulsating DC Direct Current voltage. The single phase rectifiers are classified basically into two types that are half wave rectifier and full wave rectifier. Half wave rectifiers are those which convert one-half cycle of AC voltage into DC voltage, while full wave rectifiers are those which utilize positive half cycle as well as the negative half cycle for generation of pulsating DC voltage. In our previous article, we have discussed diodes and their types. A question emerges in this context that why diode is considered as the backbone of various electronic devices and circuits?

Please refresh the browser and try again. If the problem persists please contact us. 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. The simplest rectifiers, called half-wave rectifiers, work by eliminating one side of the AC, thereby only allowing one direction of current to pass through. Since half of the AC power input goes unused, half-wave rectifiers produce a very inefficient conversion. A more efficient conversion alternative is a full-wave rectifier, which uses both sides of the AC waveform. For information on how half-wave and full-wave rectifiers operate, look here.

AC Motor Control Basics

In both cases, rectification is performed by utilizing the characteristic that current flows only in the positive direction in a diode. Full-wave rectification rectifies the negative component of the input voltage to a positive voltage, then converts it into DC pulse current utilizing a diode bridge configuration. In contrast, half-wave rectification removes just the negative voltage component using a single diode before converting to DC. From this, it can be said that full-wave rectification is a more efficient method than half-wave rectification since the entire waveform is used. Also, a ripple voltage that appears after smoothing will vary depending on the capacitance of this capacitor and the load.

You may wonder how power lines send electric currents across long distances for different purposes. And there are different "types" of electricity. The electricity that powers electric railway systems may not be appropriate for household appliances like phones and television sets. Rectifiers help by converting between these different types of electricity. Rectifiers let you convert from alternating current AC to direct current DC. AC is current that switches between flowing backwards and forwards at regular intervals while DC flows in a single direction.

What is a Bridge Rectifier : Circuit Diagram & Its Working

Rectifiers are used in a variety of devices and can be applied to modify network systems. They are categorised in different ways dependent on factors such as type of supply, bridge configuration and components used. On the whole, rectifiers can be classified into two types — single phase and three phase. Drilling down another level, they can then be separated into half wave, full wave and bridge rectifiers. Before we get into the different types of rectifiers, it is worth going over what rectifiers are. A rectifier is a diode which converts alternating current known as AC to direct current DC. DC only flows in one direction whereas AC regularly reverses direction. Rectifiers allow current to flow in a single direction.

Half-wave Rectifier Explained

Essentially, a rectifier is an electrical device used to convert alternating current AC into direct current DC by allowing a current to flow through the device in one direction only. Diodes work like one-way valves within the rectifier to maintain this flow of current. Rectification is the general way to describe this process. While rectifiers have many uses, they are most often used as the primary components of DC power supplies and high-voltage direct current transmission systems. Ripple is an important measurement for determining the efficiency of a rectifier.

In electronics, Rectifier circuit is the most used circuit because almost every electronic appliance operates on DC Direct Current but the availability of the DC Sources are limited such as electrical outlets in our homes provide AC Alternating current. Even our cell phone chargers use rectifiers to convert the AC from our home outlets to DC. Different types of Rectifiers are used for specific applications. We mainly have two types of voltage types present that are widely used these days.
