A bridge rectifier is an electronic circuit that converts AC electrical power into DC electrical power. It is a form of rectifier, which is an electronic device that converts alternating current to direct current. The GBU406 is one type of bridge rectifier. This article will discuss the application field and working principle of the GBU406.

Application Field of GBU406

The GBU406 is a type of full-wave rectifier which is suitable for use in a variety of applications. It can be used in high-frequency, low-power DC/DC converter, switching power supplies and various applications requiring rectification with lower power. The GBU406 is also well-suited for AC to DC conversion in remote-controlled systems, communication systems and many other modern digital systems.

Working Principle of GBU406

The basic principle of bridge rectifiers is to take the AC input signal and convert it into a DC signal. According to the structure and composition of the bridge rectifier, its working principle can be divided into two types: a two-diode bridge rectifier and a four-diode bridge rectifier. The GBU406 is a four-diode bridge rectifier.

The four-diode bridge rectifier basically consists of two electrical circuties connected in a bridge configuration. The upper two diodes are connected in series, and the lower two diodes are also connected in series. When alternating current flows through the bridge rectifier, each diode will perform a reverse current blocking. During the positive half cycle of the AC sine wave, the upper previously mentioned two diodes will open the forward current, and the other two diodes will open the reverse current. Similarly, during the negative half cycle of the AC sine wave, the two lower diodes will open the forward current, and the other two diodes will open the reverse current.

Through the above alternation, the bridge rectifier can convert the alternating current into a direct current. Finally, the DC output voltage of the four-diode bridge rectifier can make the average voltage of the AC sine wave twice as high as the peak voltage.

Conclusion

In conclusion, the GBU406 is a type of full-wave rectifier which is suitable for use in a variety of applications. It mainly converts AC power into DC power by using two pairs of four diodes. Each diode performs a reverse current blocking in either the positive or negative cycle of the AC sine wave, thus converting alternating current into direct current. The GBU406 is well-suited for AC to DC conversion in remote-controlled systems, communication systems and many other modern digital systems.
