What is Rectifier?

RECTIFIER DEFINITION AND TYPES: Some devices are designed to work with DC voltage. In order to work these devices, the AC mains sign must be converted into a DC sign with Rectifier. Rectifier and SMPS are used to obtain DC signals. There is 4 type of Rectifier according to the conversion process;

a- Uncontrolled type Rectifier: This type of Rectifier, consisting of a transformer and a bridge diode, is widely sold in the sector because they are very cheap. But, they are risky for the devices and batteries, because the output voltage is constantly variable.

b- Step-type rectifier: This rectifier is more reliable than uncontrolled type rectifier, but still the output ivoltage is controlled by the user, so they are risky rectifier for devices.

c- Variac controlled rectifier : Since the output voltage is controlled with the variac, the output is stable. However, they are heavy and cumbersome rectifiers.

d- Thyristor Controlled Rectifier: Details are described below.



Artsan Energy continues to improve itself with the giving importance to customer satisfaction.

Rectifiers detail


Since they give a better quality DC compared to other types of rectifiers, it is the more preferred rectifier. Batteries connected to this type of rectifier will have a longer life. Likewise, devices connected to this type of rectifier work more efficiently and have a longer life. The electronic control card continuously controls the output voltage and current, triggering the thyristors at an appropriate angle and obtaining the desired dc voltage. Thus, the output voltage will be stable by changing the trigger angle when there is change on the mains voltage and loads, quality sign is obtained with the filters used at the output.

The working principle of 3 Phase Input Rectifier is almost like 1 Phase Input Recitifer. However, 3 Phase Rectifier has a better quality output signal than 1 Phase Recitifier. Normally, 3 Phase rectifiers are rectified with 6 pulses.

3 Phase Rectifier, 12 pulse and 18 pulse rectifier groups give better quality output signals compared to 6 pulse rectifier and minimizing mains harmonics. However, this type of rectifier prices are more expensive, so they are not preferred unless it is necessary. Our 3 Phase Input Recitifiers rectifies 6 pulse as standart, we can produce 12 pulse rectifier if requested.

In addition to standard rectifiers, Artsan Energy can design and manufacture all kinds of special rectifier according to the demand with its engineers and technicians.
