Diodes - Bridge Rectifiers

Bridge rectifiers are some of the most commonly used rectifiers in electronics. They are relatively inexpensive and can handle high currents, making them quite popular. The 3N247 is a bridge rectifier that is used in various applications, such as DC-to-AC conversion, voltage stabilisation, and rectifying alternating current. In this article, we will discuss the application field of the 3N247, as well as how it works.

Application Field of the 3N247

The 3N247 is a type of diode bridge rectifier, meaning it is used to convert alternating current (AC) input into direct current (DC) output. It is composed of 4 diodes arranged in a “bridge” pattern.The 3N247 can be used in a range of different applications, including DC-to-AC conversion, voltage stabilisation, motor speed regulation, and ripple filtering. It can also be used in power supply design, where it is used to rectify AC input and provide DC output. As the 3N247 is relatively small in size and can handle large amounts of current, it is an ideal choice for many power supply designs.

Working Principle of the 3N247

The 3N247 is a four diode bridge rectifier. It has two positive inputs, labeled A and C, and two negative inputs, labeled B and D.The bridge rectifier works by having two diodes (A and B) conducting current during the positive half cycle, and two diodes (C and D) conducting current during the negative half cycle. As the current flows through the four diodes, it alternates direction each half cycle, resulting in DC output.The 3N247 is a full-wave rectifier, meaning it rectifies both halves of the AC waveform, making it more efficient than a half-wave rectifier.

Conclusion

The 3N247 is a bridge rectifier that is commonly used in various applications, such as DC-to-AC conversion, voltage stabilisation, and rectifying alternating current. It works by having two diodes conducting current during the positive half cycle, and two diodes conducting current during the negative half cycle, resulting in DC output. The 3N247 is a full-wave rectifier, making it more efficient than a half-wave rectifier.
