Leading Rectifier Manufacturers

A rectifier is an electrical device that converts alternating current into direct current. The direct current flows in one direction, and the inverter performs the reverse operation. The straightening of the current direction is known as rectification. Read More…

Rectifier A rectifier contains sets of diodes that change AC power into DC power, allowing current to flow in one direction but not in the other. This process is known as rectification.

What is a Rectifier?

The physical appearance of rectifiers has numerous forms such as wet chemical cells, selenium oxide plates, mercury arc valves, stacks of copper, semiconductor diodes, vacuum tube diodes, and silicon controlled rectifiers.


Rectifiers consist of many different uses, but they are mostly used as direct current transmission system components. They are also used as power transmission systems for direct currents with very high voltages.

Other than its use as a direct current generator, rectification can also be used as a source of power. Rectifiers are also used to detect flames when dealing with gas heating systems.

How Rectifiers Function

Half wave rectifiers, which are the simplest type, function by eliminating one part or half of the alternating current.This will allow only a single direction of current to pass through.

These half wave rectifiers, however, produce very inefficient output of direct current. This is because almost half of the alternating current is not being used in the rectification process.

The process of full wave rectification is more efficient as compared to the former, and it produces a very high output. This is because all of the input alternating current waveform is being used.

Types of Rectifiers

Rectifiers are grouped into many designs depending on a number of factors, such as components used, nature of control, and bridge configuration. The majority of them, however, are classified as single phase and three phase rectifiers.

Additionally, the rectifiers are divided under controlled and uncontrolled. Uncontrolled rectifiers are those whose output voltage cannot be controlled.

Half Wave Rectifier

Half Wave Rectifier Circuit

When using a half wave rectifier after the alternating current is applied to the input, the negative half circle is blocked while the positive half circle is the one which is visible across the load.

The requirements needed here are a single diode in a single phase supply and three diodes in a three phase supply. The circuits of the half wave rectifier need continuous filtration to reduce harmonics of the alternating current.

Full Wave Rectifier

On a full wave rectifier, the current in the load flows in one direction when the alternating current is applied to the input. The resulting output voltage produced by this circuit is high as compared to the former.

Full Wave Rectifier Circuit

This is achieved by making use of both the polarities of the input current to yield the direct current. The requirements for this rectifier are two diodes. A full wave rectifier can further be classified into the two below:

Bridge Rectifier

A bridge rectifier consists of four diodes which are used to change all of the alternating current into the output direct current. The output consists of fewer ripples than that of a half wave rectifier, but it is not stable or level.

Tapped Full Wave Rectifier

This rectifier makes use of a transformer that consists of a secondary winding at the tapped center point. It also uses two diodes that are connected to the circuit.

Tapped Rectifier Circuit

Each of the diodes uses half of the input current, and this circuit is highly efficient because the alternating current supplies power to both valves.

Applications and Uses of Rectifiers

Rectifiers are used to detect radio signals, which are amplitude modulated. They are also suppliers of voltage, which is polarized for welding activities.

A rectifier serves three main purposes, which are:

  • Converting alternating current to direct current
  • Changing the voltage by using a transformer
  • Converting DC back to AC current

Rectifiers are of great significance in the technological and digital world, and they are used widely inside all electronic devices and power supplies.

Choosing the Proper Rectifier Supplier

To make sure you have the most positive outcome when purchasing Rectifiers from a Rectifier Manufacturer, it is important to compare at least 6 Suppliers using our list of Rectifier manufacturers. Each Rectifier Manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each Rectifier business website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple Rectifier businesses with the same quote.
