Diodes - Bridge Rectifiers is an electrical device typically used to convert alternating current (AC) to direct current (DC). In electronics, a bridge rectifier is typically used with a power supply to convert AC to DC, and is composed of four diodes for the conversion. It is also known as a diode bridge. The 678-2 model is a type of bridge rectifier manufactured by the company, which is suitable for different electrical applications.

The 678-2 rectifier is a four-terminal semiconductor device consisting of four diodes. It consists of two anodes and two cathodes, constructed in a bridge configuration or bridge circuit to accomplish full-wave rectification. The rectifier can be attached to the ends of the power supply or to the input transformer by soldering. The circuit provides for two outputs - a positive and negative DC voltage.

operations, the 678-2 rectifier allows current to flow from the positive input terminal to the negative output terminal and from the negative input terminal to the positive output terminal. The current flows through the diodes in turn, when forward biasing is applied. However, when the current reverses its direction, the other two diodes go into reverse bias and block further current flow. This makes the bridge rectifier a very efficient device for converting alternating current to direct current.

The bridge rectifier has many application areas. Its most common application is in power supplies, where the rectifier converts the AC electricity supplied by the main power source into DC electricity. This DC power is then used to power various electrical devices. The rectifier is also used in other applications, such as in electrolytic plating or electroplating, in which it helps ionize the metal in the solution; in audio amplifiers, it reduces distortions, helping to generate a clear sound; and in motor control and DC motor speed control, in which they help regulate the speed at which motors run.

The 678-2 rectifier is an essential component for many electronic applications. Its ability to convert AC to DC power makes it an ideal choice for many power supplies. By using the bridge rectifier, manufacturers are able to produce a variety of high quality power supply products that can be used in a variety of applications.
