Diodes - Bridge Rectifiers

A bridge rectifier is an assembly of four separate diodes connected together in a structure known as a bridge circuit. It is usually used to convert an alternating current (AC) input into a direct current (DC) output. It is composed of four diodes connected in the form of a Wheatstone bridge. The MB108 bridge rectifier is a high performance diode bridge with a forward current range of 8.0A, a reverse voltage rating of 75-100V, and a surge peak current of 40A.

Working Principle

The MB108 bridge rectifier is a four-diode package used to convert an AC voltage to a DC voltage. In a bridge rectifier circuit, the AC input is connected to the diagonally opposite corners of the bridge. During the positive half cycle of the input voltage, M1 and M2 are forward biased, while M3 and M4 are reverse biased. This allows current to flow through M1, M2, and the load. During the negative half cycle of the AC voltage, M3 and M4 become forward biased and M1 and M2 become reverse biased. This allows the current to flow through M3, M4, and the load.

Application Field

The MB108 bridge rectifier has a wide variety of applications. It is commonly used in power supplies and battery chargers, as well as various inverter circuits, rectifiers and current source converters. It is also used in automotive, lighting and motor control applications. In addition, the MB108 is frequently used in electronic circuits and LED drivers.

The MB108 bridge rectifier provides an efficient and reliable rectification for many different applications. It is capable of handling a wide range of power inputs and offers a fast switching speed. Its low forward voltage and high current handling capabilities make it an ideal choice for various power supply designs.

The MB108 bridge rectifier is a versatile, robust and cost-effective solution for converting AC to DC power. It is a reliable and efficient option for powering high power loads, including motors, transformers, and other power converters.
