Diodes, also known as rectifiers, are electric parts that allow current to flow in one direction and block current from flowing in the opposite direction. Bridge rectifiers are commonly used in power supplies to convert AC (alternating current) to DC (direct current). They enable an AC signal to be converted to a DC voltage without the need of a costly transformer or complex circuitry. In this article, we will discuss the application field and working principle of BU1208-E3/51 bridge rectifier, an 800V, 1.2A dual-phase bridge rectifier.

Application Field

The BU1208-E3/51 bridge rectifier is typically used in applications such as industrial, domestic, telecommunications and power supplies. This is because the diode bridge provides the bridge rectifier\'s basic function: producing a set output voltage regardless of the input voltage (if the input voltage threshold is exceeded). In addition, it protects against reverse-voltage and over-voltage conditions and can handle high power loads. This makes it suitable for a variety of applications including home and office electronics, electrical appliances, automotive and military equipment.

The BU1208-E3/51 bridge rectifier is also suitable for power supplies, motor drives and solar energy applications since it provides high efficiency, low power loss and increased power converters.

Working Principle

When an AC voltage is applied to the bridge rectifier, the diode bridges conduct current in two pairs during the positive and negative half cycles of the AC signal. During the positive half cycle, current flows in a clockwise direction from the input voltage to the load through the two forward-biased diodes. While, during the negative half cycle, current flows in a counterclockwise direction from the input voltage to the load through two reverse-biased diodes. These actions generate a unidirectional pulsating direct current at the load.

As mentioned above, the BU1208-E3/51 bridge rectifier has a high power handling capacity. This is due to the bridge’s low forward voltage drops. Furthermore, since the bridge rectifier is rated for a high voltage of 800V, the diode bridge is able to sustain a higher average output current.

Conclusion

The BU1208-E3/51 bridge rectifier is a dual-phase bridge rectifier with a high power-handling capacity and low forward voltage drop. It is ideal for a variety of applications such as power supplies, motor drives and solar energy applications due to its suitability for high power loads and its ability to protect against over-voltage and reverse-voltage conditions. Overall, the bridge rectifier is a useful and versatile component for converting AC signals to DC voltage.
