Bridge Rectifiers

A bridge rectifier is an electrical device with four wires or terminals which converts alternating current (AC) to direct current (DC), and is often used in power supplies. Bridge rectifiers have a wide range of uses and there are a variety of bridge rectifier circuits available. The bridge rectifier is a full-wave rectification circuit composed of four diodes arranged in a "bridge" configuration.

113MT120KB Application Field and Working Principle

The 113MT120KB is a high-end, high precision bridge rectifier with a power rating of 1A at 120V. It is designed for wide-ranging applications, including AC to DC converters, DC motors, battery chargers and electronic switching. This bridge rectifier is composed of four 1A, 120V diodes connected in a half wave configuration for full wave rectification. It is a low cost and reliable device with excellent characteristics. The 113MT120KB bridge rectifier is most commonly used in variable speed DC drive applications or circuits requiring high input impedance and high efficiency.

Bridge Rectifier Circuit

Bridge rectifiers are commonly used in AC to DC circuits, and are composed of four diodes arranged in a full wave configuration. The typical bridge rectifier circuit diagram looks like this:

In this configuration, the diodes act as switches, allowing only the positive half of the AC wave to pass through the circuit and be rectified into a DC output. When the positive half of the AC wave is present, two of the diodes are forward biased and two are reverse biased. When the negative half of the AC wave is present, the forward and reverse biased diodes switch so that only the negative half of the wave is passed through the circuit.

Advantages and Disadvantages

Bridge rectifiers have a number of advantages over other rectifiers, such as their high efficiency and low cost. Additionally, these devices require fewer parts than other types of rectifiers and can be used for both AC and DC applications.

Bridge rectifiers also have some shortcomings, however. These types of rectifiers produce a pulsating DC output and require additional filtering of the output to obtain a smooth waveform. Additionally, bridge rectifiers have poorer regulation than other types of rectifiers, which can lead to voltage fluctuations.

Conclusion

Bridge rectifiers are versatile, low cost devices that are commonly used in AC to DC circuits. The 113MT120KB bridge rectifier is a reliable and cost-effective device that can be used in a variety of applications. While these types of rectifiers have some disadvantages, their advantages often outweigh them when considering their cost, versatility and high efficiency.
