D126B45CXPSA1 Application Field and Working Principle

the D126B45CXPSA1 is a fast recovery, single-phase rectifier. It is a high power, 125A rated current, and high efficiency, extensively used in industrial, telecommunications and computing fields, etc. Due to its unique and outstanding features, it is popular in major markets.

The fundamental application of a single-phase rectifier is to rectify the incoming AC (alternating current) to a DC (direct current) voltage.

Working Principle

A single-phase rectifier works by allowing electric current to flow in only one direction: from the positive end to the negative end. This prevents the negative current from reversing its flow causing a short circuit and other electrical problems. Single-phase rectifiers use a diode bridge to perform this task. The bridge consists of four diodes arranged in a symmetrical pattern allowing the current to flow in the controlled direction.

To rectify the incoming AC voltage, each of the four diodes is arranged in such a manner that only two of the diodes conduct at a given time. As the voltage polarity changes, alternating between positive and negative, the conducting diodes of the rectifier also change. This creates a controlled direct current output with very little distortion or noise (ripple).

Applications of a Single-Phase Rectifier

The rectification of electricity is the main use of a single-phase rectifier. It is used to convert AC electricity into DC electricity. This is often used in industrial applications such as welding machines, electric motors and variable speed drives. Additionally, it is typically used in power supplies for computers, telecommunications equipment, and audio-visual electronics.

The D126B45CXPSA1 is also used for its low noise and high efficiency qualities. This is especially useful in applications that are sensitive to noise such as server power supplies and other applications that require reliable power inputs.
