Diodes - Bridge Rectifiers

In modern power electronics and electrical power transmission, bridge rectifiers play an essential role. Bridge rectifiers are typically used to convert AC power to DC power. This allows for the regulated supply of power to a given device. The bridge rectifier is an essential component of any circuit that uses AC power, as it provides DC power.

What are Bridge Rectifiers?

Bridge rectifiers are a type of diode rectifier, which is an electronic component which switches on quickly when voltage is applied and switches off quickly when the voltage is removed. Bridge rectifiers are typically made up of 4 diodes, arranged in either a bridge configuration or an H-bridge configuration. The name bridge rectifier comes from the shape of the circuitry which resembles the shape of a bridge.

How do Bridge Rectifiers Work?

Bridge rectifiers work by taking alternating current (AC) and converting it into direct current (DC). This can be done by connecting a load to the output of the bridge rectifier. The four diodes act as a switch in this configuration, allowing current to flow in only one direction. The diodes act as a switch, which is opened and closed rapidly, providing the output of the bridge rectifier with an alternating current (AC).

Applications of Bridge Rectifiers

Bridge rectifiers are used in a variety of applications. Major uses include: computer power supplies, converters and motor speed controls, surge protectors, home lighting systems and electric bell ringer, point of load converters in energy storage systems, security systems, and wireless power transfer, solar panel DC-DC converters and home medical equipment.

Advantages of Bridge Rectifiers

Bridge rectifiers provide a number of advantages compared to other power conversion solutions, such as cost savings and high efficiency. They are cost effective as they require only four diodes to create a full wave rectification, whereas six or eight diodes are needed for other rectification techniques. They are also highly efficient due to the use of the four diodes, which reduce the power loss by half. In addition, bridge rectifiers provide improved output voltage stability, higher current capability, and better power factor.

695-5 Application Field and Working Principle

The 695-5 is a bridge rectifier module of a type used for many applications, such as DC-to-DC converters, surge suppressors, home lighting systems, electric bell ringers and many other uses. The 695-5 contains four standard diodes in a bridge configuration. The bridge rectifier works by converting an AC input signal into a full-wave, rectified DC output. All four diodes are connected in series, allowing current to flow in one direction only. This results in a direct current being output, which is suitable for use in many electronics applications.

Conclusion

Bridge rectifiers are essential components in electrical and power electronics systems, as they provide a reliable source of DC power. The 695-5 is a bridge rectifier which is suitable for a variety of applications, including DC-to-DC converters, surge suppressors, home lighting systems, and electric bell ringers. Bridge rectifiers offer various advantages such as cost savings, high efficiency, better output voltage stability, higher current capability, and better power factor.
